# An Exposition of the Old and New Testament (1828)/Genesis/Chapter 17

CHAP. XVII.
This chapter contains articles of agreement covenanted and concluded upon between the great Jehovah, the Father of mercies, on the one part, and pious Abram, the Father of the faithful, on the other part. Abram is therefore called the friend of God, not only because he was the man of his council, but because he was the man of his covenant; both these secrets were with him: mention was made of this covenant, ch. 15. 18, but here it is particularly drawn up, and put into the form of a covenant, that Abram might have strong consolation. Here is, I. The circumstances of the making of this covenant, the time and manner, v. 1, and the posture Abram was in, v. 3. II. The covenant itself. In the general scope of it, v. 1. And afteeward, in the particular instances. 1. That he should be the father of many nations, v. 4, 6. and, in token of that, his name was changed, v. 5. 2. That God would be a God to him and his seed, and would give them the land of Canaan, v. 7, 8. And the seal of this part of the covenant was circumcision, v. 9...14. 3. That he should have a son by Sarai, and in token of that, her name was changed, v. 15, 16. This promise Abram received, v. 17. And his request for Ishmael (v. 18.) was answered, abundantly to his satisfaction, v. 19..22. III. The circumcision of Abram and his family, according to God's appointment, v. 22..27.
1.AND when Abram was ninety years old and nine, the Lord appeared to Abram, and said unto him, I am the Almighty God; walk before me, and be thou perfect. 2. And I will make my covenant between me and thee, and will multiply thee exceedingly. 3. And Abram fell on his face: and God talked with him, saying.
Here is,
I. The time when God made Abram this gracious visit; when he was 99 years old, full 13 years after the birth of Ishmael. 1. So long, it should seem, God's extraordinary appearances to Abram were intermitted; and all the communion he had with God, was only in the usual way of ordinances and providences. Note, There are some special comforts which are not the daily bread, no not of the best saints, but they are favoured with them now and then. On this side heaven, they have convenient food, but not a continual feast. 2. So long the promise of Isaac was deferred. (1.) Perhaps to correct Abram's over-hasty marrying of Hagar. Note, The comforts we sinfully anticipate, are justly delayed. (2.) That Abram and Sarai being so far stricken in age, God's power, in this matter, might be the more magnified, and their faith the more tried. See Deut. 32. 36. John 11. 6, 15. (3.) That a child so long waited for, might be an Isaac, a son indeed, Isa. 54. 1.
II. The way in which God made this covenant with him; The Lord appeared to Abram, in the ​Shechinah, some visible display of God's immediate glorious presence with him. Note, God first makes himself known to us, and gives us a sight of him by faith, and then takes us into his covenant.
III. The posture Abram put himself into upon this occasion. He fell on his face while God talked with him, v. 3. Either, 1. As one overcome by the brightness of the divine glory, and unable to bear the sight of it, though he had seen it several times before: Daniel and John did likewise, though they were also acquainted with the visions of the Almighty, Dan. 8. 17.—10. 9, 15. Rev. 1. 17. Or, 2. As one ashamed of himself, and blushing to think of the honours done to one so unworthy: he looks upon himself with humility, and upon God with reverence, and, in token of both, falls on his face, putting himself into a posture of adoration. Note, (1.) God graciously condescends to talk with those whom he takes into his covenant and communion with himself. He talks with them by his word, Prov. 6. 22. He talks with them by his Spirit, John 14. 26. This honour have all his saints. (2.) Those that are admitted into fellowship with God, are, and must be, very humble and very reverent in their approaches to him. If we say we have fellowship with him, and the familiarity breeds contempt, we deceive ourselves. (3.) Those that would receive comfort from God, must set themselves to give glory to God, and to worship at his footstool.
IV. The general scope and summary of the covenant, laid down as the foundation on which all the rest was built; it is no other than the covenant of grace, still made with all believers in Jesus Christ, v. 1. Observe here,
1. What we may expect to find God to us; I am the Almighty God; by this name he chose to make himself known to Abram rather than by his name Jehovah, Exod. 6. 3. He used it to Jacob, ch. 35. 11. They called him by this name, ch. 28. 3.—43. 14.—48. 3; It is the name of God that is mostly used throughout the book of Job, at least thirty times in the discourses of that book. After Moses, Jehovah is more frequently used, and this very rarely; I am El-shaddai; it bespeaks the almighty power of God, either, (1.) As an avenger, from שדה he laid waste, so some; and they think God took this title from the destruction of the old world. This is countenanced by Isa. 13. 6, and Joel 1. 15. Or, (2.) As a benefactor, ש for אשר who, and די sufficient. He is a God, that is enough; or, as our old English translation reads it here very significantly, I am God all-sufficient. Note, The God with whom we have to do, is a God that is enough. [1.] He is enough in himself; he is self-sufficient; he has every thing, and he needs not any thing. [2.] He is enough to us, if we be in covenant with him: we have all in him, and we have enough in him; enough to satisfy our most enlarged desires, enough to supply the defect of every thing else, and to secure to us a happiness for our immortal souls: see Ps. 16. 5, 6.—73. 25.
2. What God requires that we be to him; the covenant is mutual, Walk before me, and be thou perfect, that is, upright and sincere; for herein the covenant of grace is well-ordered, that sincerity is our gospel perfection. Observe, (1.) That to be religious, is to walk before God in our integrity; it is to set God always before us, and to think, and speak, and act, in every thing, as those that are always under his eye. It is to have a constant regard to his word as our rule, and to his glory as our end, in all our actions, and to be continually in his fear. It is to be inward with him in all the duties of religious worship, for in them particularly we walk before God, 1 Sam. 2. 30, and to be entire for him, in all holy conversation. I know no religion but sincerity. (2.) That upright walking with God, is the condition of our interest in his all-sufficiency. If we neglect him, or dissemble with him, we forfeit the benefit and comfort of our relation to him. (3.) A continual regard to God's all-sufficiency, will have a great influence upon our upright walking with him.
4. As for me, behold, my covenant is with thee, and thou shalt be a father of many nations. 5. Neither shall thy name any more be called Abram; but thy name shall be Abraham; for a father of many nations have I made thee. 6. And I will make thee exceeding fruitful, and I will make nations of thee, and kings shall come out of thee.
The promise here is introduced with solemnity: "As for me," says the great God, "behold, behold and admire it, behold and be assured of it, my covenant is with thee;" as before, v. 2, I will make my covenant. Note, The covenant of grace is a covenant of God's own making; this he glories in, (as for me,) and so may we. Now here,
I. It is promised to Abram, that he should be a father of many nations: that is, 1. That his seed after the flesh, should be very numerous, both in Isaac and Ishmael, and in the sons of Keturah; something extraordinary is doubtless included in this promise, and we may suppose that the event answered to it, and that there have been, and are, more of the children of men descended from Abraham, than from any one man at an equal distance with him from Noah, the common root. 2. That all believers, in every age, should be looked upon as his spiritual seed, and that he should be called, not only the friend of God, but the father of the faithful. In this sense, the Apostle directs us to understand this promise, Rom. 4. 16, 17. He is the father of those in every nation, that by faith enter into covenant with God, and (as the Jewish writers express it) are gathered under the wings of the divine Majesty.
II. In token of this, his name was changed from Abram, a high father, to Abraham, the father of a multitude. This was, 1. To put an honour upon him: it is spoken of as the glory of the church, that she shall be called by a new name, which the mouth of the Lord shall name, Isa. 62. 2. Princes dignified their favourites, by conferring new titles upon them; thus was Abraham dignified by him that is indeed the Fountain of honour: all believers have a new name, Rev. 2. 17. Some think it added to the honour of Abraham's new name, that a letter of the name Jehovah was inserted into it, as it was a disgrace to Jeconiah to have the first syllable of his name cut off, because it was the same with the first syllable of that sacred name, Jer. 22. 28. Believers are named from Christ, Eph. 3. 15. 2. To encourage and confirm the faith of Abraham; while he was childless, perhaps even his own name was sometimes an occasion of grief to him: why should he be called a high father, who was not a father at all? But now that God had promised him a numerous issue, and had given him a name which signified so much, that name was his joy. Note, God calls things that are not, as though they were. It is the apostle's observation upon this very thing, Rom. 4. 17; he called Abraham the father of a multitude, because he should prove to be so in due time, though as yet he had but one child.
7. And I will establish my covenant between me and thee, and thy seed after thee, ​in their generations, for an everlasting covenant, to be a God unto thee, and to thy seed after thee. 8. And I will give unto thee, and to thy seed after thee, the land wherein thou art a stranger, all the land of Canaan, for an everlasting possession; and I will be their God. 9. And God said unto Abraham, Thou shalt keep my covenant therefore, thou, and thy seed after thee, in their generations. 10. This is my covenant, which ye shall keep, between me and you, and thy seed after thee; every man-child among you shall be circumcised. 11. And ye shall circumcise the flesh of your foreskin; and it shall be a token of the covenant betwixt me and you. 12. And he that is eight days old, shall be circumcised among you, every man-child in your generations, he that is born in the house, or bought with money of any stranger, which is not of thy seed. 13. He that is born in thy house, and he that is bought with thy money, must needs be circumcised: and my covenant shall be in your flesh for an everlasting covenant. 14. And the uncircumcised man-child, whose flesh of his fore-skin is not circumcised, that soul shall be cut off from his people; he hath broken my covenant.
Here is,
I. The continuance of the covenant; intimated in three things. 1. It is established; not to be altered or revoked: it is fixed, it is ratified, it is made as firm as the divine power and truth can make it. 2. It is entailed; it is a covenant, not with Abraham only, (then it would die with him,) but with his seed after him, not only his seed after the flesh, but his spiritual seed. 3. It is everlasting in the evangelical sense and meaning of it. The covenant of grace is everlasting; it is from everlasting in the counsels of it, and to everlasting in the consequences of it; and the external administration of it is transmitted with the seal of it to the seed of believers, and the internal administration of it by the Spirit, to Christ's seed in every age.
II. The contents of the covenant; it is a covenant of promises, exceeding great and precious promises. Here are two, which, indeed, are all sufficient. 1. That God would be their God, v. 7, 8. All the privileges of the covenant, all its joys, and all its hopes, are summed up in this: a man needs desire no more than this, to make him happy. What God is himself, that he will be to his people; his wisdom their's, to guide and counsel them; his power their's, to protect and support them; his goodness their's, to supply and comfort them. What faithful worshippers can expect from the God they serve, believers shall find in God as their's. This is enough, yet not all. 2. That Canaan should be their everlasting posession, v. 8. God had before promised this land to Abraham, and his seed, ch. 15. 18. But here, where it is promised for an everlasting possession, surely it must he looked upon as a type of heaven's happiness, that everlasting rest which remains for the people of God, Heb. 4. 9. This is that better country to which Abraham had an eye, and the grant of which was that which answered to the vast extent and compass of that promise, that God would be to them a God; so that if God had not prepared and designed this, he would have been ashamed to be called their God, Heb. 11. 16. As the land of Canaan was secured to the seed of Abraham, according to the flesh, so heaven is secured to all his spiritual seed, by a covenant, and for a possession, truly everlasting. The offer of this eternal life is made in the word, and confirmed by the sacraments, to all that are under the external administration of the covenant; and the earnest of it is given to all believers, Eph. 1. 14. Canaan is here said to be the land wherein Abraham was a stranger; and heaven is a land to which we are strangers, for it does not yet appear what we shall be.
III. The token of the covenant, and that is circumcision, for the sake of which the covenant is itself called the covenant of circumcision, Acts 7. 8. It is here said to be the covenant which Abraham and his seed must keep, as a copy or counterpart, v. 9, 10. It is called a sign and seal, Rom. 4. 11, for it was, 1. A confirmation to Abraham and his seed, of those promises which were God's part of the covenant, assuring them that they should be fulfilled; that in due time Canaan should be their's: and the continuance of this ordinance, after Canaan was their's, intimates that that promise looked further, to another Canaan, which they must still be in expectation of: see Heb. 4, 8. 2. An obligation upon Abraham and his seed, to that duty which was their part of the covenant; not only to the duty of accepting the covenant and consenting to it, and the putting away of the corruption of the flesh, (which were more immediately and primarily signified by circumcision,) but, in general, to the observation of all God's commands, as they should at any time hereafter be intimated and made known to them; for circumcision made men debtors to do the whole law, Gal. 5. 3. They who will have God to be to them a God, must consent and resolve to be to him a people.
Now, (1.) Circumcision was a bloody ordinance; for all things by the law were purged with blood, Heb. 9. 22. See Exod. 24. 8. But the blood of Christ being shed, all bloody ordinances are now abolished; circumcision therefore gives way to baptism. (2.) It was peculiar to the males; though the women also were included in the covenant, for the man is the head of the woman. In our kingdom, the oath of allegiance is required only from men: some think that the blood of the males only was shed in circumcision, because respect was had in it to Jesus Christ, and his blood. (3.) It was the flesh of the fore-skin that was to be cut off, because it is by ordinary generation that sin is propagated, and with an eye to the Promised Seed, who was to come from the loins of Abraham. Christ having not yet offered himself for us, God would have man to enter into covenant by the offering of some part of his own body, and no part could be better spared. It is a secret part of the body: for the true circumcision is that of the heart: this honour God put upon an uncomely part, 1 Cor. 12. 23, 24. (4.) The ordinance was to be administered to children when they were eight days old, and not sooner: that they might gather some strength to be able to undergo the pain of it, and that at least one sabbath might pass ever them. (5.) The children of the stranger, of whom the master of the family was the true domestic owner, were to be circumcised, v. 12, 13, which looked favourably upon the gentiles, who should, in due time, be brought into the family of Abraham by faith: see Gal. 3. 14. (6.) The religious observance of this institution was required, under a very severe penalty, v. 14. The contempt of circumcision was a contempt of the covenant; if the parents did not circumcise their children, it was at their peril, as in the case of Moses, Exod. 4. 24, 25. With respect to those that were ​not circumcised in their infancy, if, when they grew up, they did not themselves come under this ordinance, God would surely reckon with them. If they cut not off the flesh of their fore-skin, God would cut them off from their people. It is a dangerous thing to make light of divine institutions, and to live in the neglect of them.
15. And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but Sarah shall her name be. 16. And I will bless her, and give thee a son also of her: yea, I will bless her, and she shall be a mother of nations; kings of people shall be of her. 17. Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is an hundred years old? And shall Sarah, that is ninety years old, bear? 18. And Abraham said unto God, O that Ishmael might live before thee! 19. And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him. 20. And as for Ishmael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation. 21. But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year. 22. And he left off talking with him, and God went up from Abraham.
Here is,
I. The promise made to Abram of a son by Sarai, that son in whom the promise, made to him, should be fulfilled, that he should be the father of many nations; for she also shall be a mother of nations, and kings of people shall be of her, v. 16. Note, 1. God reveals the purposes of his good-will to his people by degrees. God had told Abraham, long before, that he should have a son by Sarai. 2. The blessing of the Lord makes fruitful, and adds no sorrow with it, no such sorrow as was in Hagar's case. "I will bless her with the blessing of fruitfulness, and then thou shalt have a son of her." 3. Civil government and order are a great blessing to the church. It is promised, not only that people, but kings of people, should be of her; not a headless rout, but a well-modelled, well-governed society.
II. The ratification of this promise was the change of Sarai's name into Sarah, v. 15, the same letter added to her name that was to Abraham's, and for the same reasons. Sarai signifies my princess, as if her honour were confined to one family only; Sarah signifies a princess, namely of multitudes; or, signifying that from her should come the Messiah, the Prince, even the Prince of the kings of the earth.
III. Abraham's joyful, thankful entertainment of this gracious promise, v. 17. Upon this occasion, he expressed, 1. Great humility; he fell on his face. Note, The more honours and favours God confers upon us, the lower we should be in our own eyes, and the more reverent and submissive before God. 2. Great joy; he laughed, it was a laughter of delight, not of distrust. Note, Even the promises of a holy God, as well as his performances, are the joys of holy souls; there is the joy of faith, as well as the joy of fruition. Now it was that Abraham rejoiced to see Christ's day; now he saw it, and was glad, John 8. 56, for as he saw heaven in the promise of Canaan, so he saw Christ in the promise of Isaac. 3. Great admiration ; Shall a child be born to him that is an 100 years old? He does not here speak of it as at all doubtful, (for we are sure that he staggered not at the promise, Rom. 4. 20.) but as very wonderful, and that which could not be effected but by the almighty power of God, and as very kind, and a favour which was the more affecting and obliging for this, that it was extremely surprising, Ps. 126. 1, 2.
IV. Abraham's prayer for Ishmael, v. 18, O that Ishmael might live before thee! This he speaks, not as desiring that Ishmael might be preferred before the son he should have by Sarah; but, dreading lest he should be abandoned and forsaken of God, he puts up this petition on his behalf. Now that God is talking with him, he thinks he has a very fair opportunity to speak a good word for Ishmael, and he will not let it slip. Note, 1. Though we ought not to prescribe to God, yet he gives us leave, in prayer, to be humbly free with him, and particular in making known our requests, Phil. 4. 6. Whatever is the matter of our care and fear, should be spread before God in prayer. 2. It is the duty of parents to pray for their children, for all their children, as Job, who offered burnt-offerings, according to the number of them all, Job 1. 5. Abraham would not have it thought, when God promised him a son by Sarah, which he so much desired, that then his son by Hagar was forgotten; no, still he bears him upon his heart, and shows a concern for him. The prospect of further favours must not make us unmindful of former favours. 3. The great thing we should desire of God for our children, is, that they may live before him, that is, that they may be kept in covenant with him, and may have grace to walk before him in their uprightness; spiritual blessings are the best blessings, and which we should be most earnest with God for, both for ourselves, and others. Those live well, that live before God.
V. God's answer to his prayer; and it is an answer of peace; Abraham could not say that he sought God's face in vain.
1. Common blessings are secured to Ishmael, v. 20, As for Ishmael, whom thou art in so much care about, I have heard thee; he shall find favour for thy sake; I have blessed him, that is, I have many blessings in store for him. (1.) His posterity shall be numerous; I will multiply him exceedingly, more than his neighbours: this is the fruit of the blessing, as that, ch. 1. 28. (2.) They shall be considerable; twelve princes shall he beget: we may charitably hope that spiritual blessings also were bestowed upon him, though the visible church was not brought out of his loins, and the covenant was not lodged in his family. Note, Great plenty of outward good things is often given to those children of godly parents, who are born after the flesh, for their parents' sake.
2. Covenant-blessings are reserved for Isaac, and appropriated to him, v. 19, 21. If Abraham, in his prayer for Ishmael, meant that he would have the covenant made with him, and the Promised Seed to come from him; then, God did not answer him in the letter, but in that sense which was equivalent, nay, which was every way better. (1.) God repeats to him the promise of a son by Sarah; she shall bear thee a son indeed. Note, [1.] Even true believers need to have God's promises doubled and repeated to them, that they may have strong consolation, Heb. 6. 18. [2.] Children of the promise are children indeed. (2.) He names that child, ​calls him Isaac, Laughter; because Abraham rejoiced in spirit, when this son was promised him. Note, If God's promises be our joy, his mercies promised shall in due time be our exceeding joy. Christ will be Laughter to them that look for him; they that now rejoice in hope, shall shortly rejoice in having that which they hope for: this is laughter that is not mad. (3.) He entails the covenant upon that child; I will establish my covenant with him. Note, God takes whom he pleases into covenant with himself, according to the good pleasure of his will: see Rom. 9. 8, 18. Thus was the covenant settled between God and Abraham, with its several limitations and remainders, and then the covenant ended; God left off talking with him, and the vision disappeared, God went up from Abraham. Note, Our communion with God here is broken and interrupted; in heaven it will be a continual and everlasting feast.
23. And Abraham took Ishmael his son, and all that were born in his house, and all that were bought with his money, every male among the men of Abraham's house; and circumcised the flesh of their fore-skin in the self-same day, as God had said unto him. 24. And Abraham was ninety years old and nine, when he was circumcised in the flesh of his fore-skin. 25. And Ishmael his son was thirteen years old when he was circumcised in the flesh of his fore-skin. 26. In the self-same day was Abraham circumcised, and Ishmael his son. 27. And all the men of his house, born in the house, and bought with money of the stranger, were circumcised with him.
We have here Abraham's obedience to the law of circumcision; he himself, and all his family, were circumcised; so receiving the token of the covenant, and distinguishing themselves from other families that had no part nor lot in the matter. 1. It was an implicit obedience; he did as God said unto him, and did not ask why or wherefore. God's will was not only a law to him, but a reason; he did it, because God bid him. 2. It was a speedy obedience; in the self-same day, v. 23, 26. Sincere obedience is not dilatory, Ps. 119. 60. While the command is yet sounding in our ears, and the sense of duty is fresh, it is good to apply ourselves to it immediately, lest we deceive ourselves by putting it off to a more convenient season. 3. It was an universal obedience; he did not circumcise his family, and excuse himself, but set them an example; nor did he take the comfort of the seal of the covenant to himself only, but desired that all might share with him in it: this is a good example to masters of families; they and their houses must serve the Lord. Though God's covenant was not established with Ishmael, yet he was circumcised; for children of believing parents, as such, have a right to the privileges of the visible church, and the seals of the covenant, whatever they may prove afterward; Ishmael is blessed, and therefore circumcised. 4. Abraham did this, though much might be objected against it: though circumcision was painful, though to grown men it was shameful; though, while they were sore and unfit for action, their enemies might take advantage against them, as Simeon and Levi did against the Shechemites; though Abraham was 99 years old, and had been justified and accepted of God long since; though so strange a thing done religiously, might be turned to his reproach by the Canaanite and the Perizzite that dwelt then in the land; yet God's command was sufficient to answer these, and a thousand such objections; what God requires, we must do, not conferring with flesh and blood.
