If one vows to bring a meal offering of a tenth of an ephah, he is obligated to bring a meal offering of that volume. If one vows to bring tenths of an ephah, he must bring two-tenths of an ephah, as that is the minimum plural amount. If one says that when he stated his vow to bring a meal offering he specified a certain amount but subsequently forgot how many tenths he specified, the halakha is that he must bring sixty-tenths of an ephah, which is the largest amount for a single meal offering, and stipulate that the amount of the meal offering that corresponds to his vow is dedicated to fulfilling his obligation, whereas the rest is rendered a voluntary meal offering. Some hold that he must bring sixty different meal offerings, each of a different number of tenths, from one to sixty. With regard to one who vows to bring a certain type of meal offering and subsequently forgot which type, the halakha is that he must bring all five types of meal offerings: A meal offering of fine flour, a shallow-pan meal offering, a deep-pan meal offering, a meal offering baked in an oven as loaves, and a meal offering baked in an oven as wafers. If one forgot both the type and the amount, he must bring sixty-tenths of an ephah of each of these five types of meal offerings. He is not required to bring a meal offering brought with libations, as presumably the person did not intend to bring a type of meal offering that is normally brought only with an animal offering. If one vows to bring a meal offering, or to bring a type of meal offering, but did not specify which type, the Sages disagree as to whether he may bring any meal offering of his own choosing, or whether he must bring a fine-flour meal offering. If one vows to bring meal offerings, he must bring two meal offerings. If one vows to bring meal offerings of a certain type, he must bring two meal offerings of the same type. If one vows to bring types of meal offerings, he must bring two meal offerings of two different types. Several principles of vows detailed in this chapter with regard to meal offerings also apply to other types of sacrificial vows and vows of consecration to the Temple treasury. For example, one who did not specify the quantity of the item he vowed to consecrate must bring the minimum amount that his vow indicates. If he specified the amount and subsequently forgot, he must bring the maximum amount that he could have reasonably stated. The chapter concludes with halakhot concerning the temple of Onias. If one vows to bring an offering and sacrifices it in the temple of Onias, not only is he liable to receive the punishment of karet for sacrificing an offering outside the Temple, but he also has not fulfilled his vow. If one vowed to bring an offering to the temple of Onias, or any other place outside of the Temple, and he did in fact sacrifice it there, he has fulfilled his vow, but he is still liable to receive karet for sacrificing an offering outside the Temple. He must bring the offering to the Temple ab initio. There is a dispute as to whether the temple of Onias was a temple of idol worship or was devoted to the worship of God. If a priest slaughtered an idolatrous offering and subsequently repented, he is fit to sacrifice offerings in the Temple in Jerusalem. By contrast, if he performed an idolatrous rite that is a sacrificial rite when performed in the Temple, he is no longer fit to perform service in the Temple ever again. The tractate concludes with praise of Torah scholars, and with the message that the most important issue in the service of God is not how many offerings one brings, but his intent. Provided one directs his heart toward Heaven, bringing a substantial offering and bringing a meager offering are equal in the eyes of God.
