PRIMARY LABOUR.1 HE WHO PERFORMS MANY LABOURS BELONGING TO THE SAME CATEGORY OF WORK2 IS LIABLE TO ONE SIN-OFFERING ONLY.
GEMARA. Why does he [the Tanna] state, A GREAT PRINCIPLE? Shall we say that because he wishes to teach 'another principle',3 he [therefore] states here, A GREAT PRINCIPLE?4 And in respect to shebi'ith5 too, because he wishes to teach another principle, he states, This is a great principle?6 But what of tithes, though 'another principle' is taught, he nevertheless does not teach [elsewhere] 'a great principle'?7 — Said R. Jose b. Abin: As for the Sabbath and shebi'ith, since they possess both primaries and derivatives,8 he teaches GREAT; but in respect to tithes, since there are no primaries and derivatives, he does not teach great'. Then according to Bar Kappara, who did learn 'A great principle' in respect to tithes,9 what primaries and what derivatives are there? But surely this must be the reason:10 The penal scope of the Sabbath is 'greater' than that of shebi'ith, for whereas [the restriction of] the Sabbath is found in respect of both detached and growing [produce], [the prohibitions of] shebi'ith do not operate in respect of detached, but only in respect of growing [produce].11 Again, the penal scope of the seventh year is 'greater' than that of tithes: for whereas [the law of] shebi'ith applies to both human food and animal fodder, [the law of] tithes operates in the case of human food, but not of animal fodder.12 And according to Bar Kappara who learned 'a great principle' in connection with tithes, — the penal scope of tithes is greater than that of pe'ah:13 for whereas [the law of] tithes operates in figs and vegetables [too], pe'ah does not operate in figs and vegetables.14 For we learnt: A general principle was stated in respect to pe'ah: whatever is a foodstuff, is guarded, grows from the earth, is [all] gathered simultaneously,15 and is collected for storage,16 is liable to pe'ah. 'Foodstuff' excludes the aftergrowth of woad17 and madder;18 'is guarded' excludes hefker;19 'grows from the earth' excludes mushrooms and truffles;20 'is [all] gathered simultaneously' excludes the fig-tree;21 'and is taken in to be stored' excludes vegetables.22 Whereas in respect to tithes we learnt: A general principle was stated in respect to tithes: Whatever is a foodstuff, is guarded, and grows from the earth is subject to tithes; but we did not learn, 'is gathered simultaneously and is collected for storage.
Rab and Samuel both maintain: Our Mishnah treats of a child who was taken captive among Gentiles, or a proselyte who became converted in the midst of Gentiles.23 But if one knew and subsequently forgot, he is liable [to a sin-offering] for every Sabbath.24 We learnt: HE WHO FORGETS THE ESSENTIAL LAW OF THE SABBATH: surely that implies that he knew [it] originally? — No: what is meant by HE WHO FORGETS THE ESSENTIAL LAW OF THE SABBATH? That the very existence of the Sabbath was unknown25 to him. But what if he knew and subsequently forgot; he is liable for every Sabbath? Then instead of teaching, HE WHO KNOWS THE ESSENTIAL LAW OF THE SABBATH AND PERFORMS MANY LABOURS ON MANY SABBATHS, INCURS A SIN-OFFERING ON ACCOUNT OF EACH SABBATH: let him teach, He who knew and subsequently forgot, and how much more so this one? — What is meant by, HE WHO KNOWS THE ESSENTIAL LAW OF THE SABBATH? That he who knew the essential law of the Sabbath and forgot it.
The general principle is this: a sin-offering in connection with the Sabbath is incurred for every unwitting transgression. The number of transgressions is determined by the number of unknown facts. Thus, when one is ignorant of the Sabbath law altogether, he is unaware of a single fact, and incurs one sin-offering only. If he forgets a number of Sabbaths, each is a separate fact; hence he is liable for each. If he knows that it is the Sabbath but forgets that certain labours are forbidden, each labour is a separate fact, and he is liable for each separately. — For primary (Heb. ab, lit., 'father') labours v. p. 3, n. 2.
I.e., all derivatives (toledoth) of the same primary labour (ab).
By contrast, this being wider in scope.

V. infra 73a seq. Agricultural labour forbidden during the seventh year is likewise divided into primaries and derivatives: sowing, harvesting, reaping and fruit gathering, are primaries, other forms of labour in a field or vineyard are derivatives; v. M.K. 3a.
In his collection of Baraithas. These are collections of Tannaitic teachings not incorporated by R. Judah ha-Nasi in the Mishnah; there were several such collections, the most authoritative being those of R. Hiyya and R. Oshaia.
Why GREAT is stated in connection with Sabbath.
Thus: one must do no work on growing (lit., attached') produce on the Sabbath, e.g., sow, reap, etc., nor on detached produce, e.g., grind corn. But only the former is forbidden in the seventh year, not the latter.
Thus the scope of both the Sabbath and shebi'ith is greater than that of tithes, and for that reason 'great' is employed in connection with the first two.
'Penal scope', Heb. 'onesh, is employed here in the sense that the violation of these laws is punishable.
I.e., the whole of the crop ripens about the same time.
Lit., 'is brought in to be kept'. This applies to cereals in general, which are stored in granaries over long periods.

Though these grow in the earth, they were held to draw their sustenance mainly from the air.
Whose fruits do not all ripen at the same time. The same holds good of many other trees, which are likewise excluded.
Which must be consumed whilst fresh.
So that they never knew the laws of the Sabbath.
He is regarded as knowing the sanctity of the Sabbath but forgetting on each occasion that it is the Sabbath.
What if he did not forget it?1 He is liable for each labour? Then instead of teaching, HE WHO KNOWS THAT IT IS THE SABBATH AND PERFORMS MANY LABOURS ON MANY SABBATHS, IS LIABLE FOR EVERY LABOUR, let him teach, He who knows the essential law of the Sabbath, and how much more so this case? Rather our Mishnah refers to one who knew but subsequently forgot, and Rab and Samuel's [ruling] too is similar to the case of one who knew but subsequently forgot, and it was thus stated: Rab and Samuel both maintain: Even a child who was taken captive among Gentiles or a proselyte who became converted in the midst of Gentiles is as one who knew but subsequently forgot, and so he is liable. But R. Johanan and Resh Lakish maintain: Only one who knew but subsequently forgot [is liable], but a child who was taken captive among Gentiles, or a proselyte who became converted in the midst of Gentiles, is not culpable.
An objection is raised: A great principle is stated in respect to Sabbath: He who forgets the essential law of Sabbath and performs many labours on many Sabbaths, incurs one sin-offering only. E.g., if a child is taken captive among Gentiles or a proselyte is converted in the midst of Gentiles and performs many labours on many Sabbaths, he is liable to one sin-offering only. And he is liable to one [sin-offering] on account of blood, one on account of heleb,2 and one on account of idolatry.3 But Monabaz exempts him. And thus did Monabaz argue before R. Akiba: Since a wilful transgressor is designated a sinner, and an unwitting transgressor [too] is designated a sinner;4 then just as wilful transgression implied that he had knowledge,5 so when unwittingly transgressing he must have had the knowledge.6 Said R. Akiba to him, Behold, I will add to your words. If so, just as wilful transgression involves that he shall have had knowledge at the time of his deed, so in unwitting transgression he must have had knowledge at the time of his deed.7 Even so, he replied, and all the more so since you have added [this argument]. As you define it,8 such is not designated unwitting, but wilful transgression, he retorted. Now after all it is stated, 'E.g., if a child' [etc.]: as for Rab and Samuel, it is well.9 But according to R. Johanan and Resh Lakish it presents a difficulty? — R. Johanan and Resh Lakish can answer you: Is there not Monabaz who declares him non-culpable? We rule as Monabaz.
Sc. the essential law of the Sabbath, but merely that that particular day was the Sabbath.
I.e., for the violation of each law, which if deliberately infringed, carries with it the penalty of kareth, he incurs one sin-offering only, no matter how many times he actually infringes it. The consumption of blood and heleb and the worshipping of idols are given as examples.
For a wilful trangressor v. Lev. V, 1: And if any one sin, etc. That refers to wilful transgression, since Scripture does not maintain that his sin be hidden from him', i.e., committed in ignorance. For unwitting transgression v. Lev. IV, 2 et passim.
of the forbidden nature of his action.
Formerly, though at the time of sinning he had forgotten it.
Lit., 'according to your words'.
For they too maintain that he is liable. Now, they can argue that the same holds good even if one originally knew the law but subsequently forgot it, just as they explain the Mishnah, while the particular illustration is given because of Monabaz's dissent in this case.
The analogy on mere grounds of logic is insufficient, since wilful and unwitting transgression are obviously dissimilar.
Ibid. 30; this obviously applies to deliberate transgression.
I.e., Scripture itself intimates by this proximity that the two are similar.
Before a sin-offering is incurred.
