Though he is fruitful among his brothers, an east wind will come, The breath of Yahweh coming up from the wilderness; And his spring will become dry, And his fountain will be dried up. He will plunder the storehouse of treasure.
We are then taught here, that when God for a time blesses us, we must beware lest we abuse his favour and entertain a false confidence, as we see that Ephraim had done: for he flourished among his brethren, and then raised up his head; and thus he obliterated God’s favour through his pride and haughtiness. We ought then, when prosperous, ever to fear, lest something like this should happen to us. The more kindly then God deals with us, the more constantly ought we to be roused up to pray to him, that he may be pleased to carry on his work to the end, lest we slumber in our enjoyments while God is indulgent to us. This, in the first place, we ought to bear in mind. Then we must also notice the warning of the prophet, that God can suddenly, and, as it were, in a moment, upset the prosperity of men, that there is nothing in this world which cannot be immediately changed whenever God withdraws from us his favour. This comparison then ought often to occur to us; when the air is tranquil, when the season is quiet, a wind will in a moment rise up, which will dry the earth, which will also make dry the fountains; and yet the vigour of fountains seems to be perpetual; what then may not happen to us? Cannot the Lord at any moment make us dry, since we have in ourselves no source of strength? He might indeed have said in this place what we find in the 40th chapter of Isaiah (98) that man is like the flower that soon fadeth; but he intended to express something more profound; for this people, being deeply fixed in their own strength, thought that they were supplied by exhaustless fountains, and that their vigour could not be dried up: hence he says, “Though thou hast fountains and springs, yet God will dry thee up; for he will find a wind that has power, as experience proves, to dry up springs and fountains.”
