If menahot and libation-offerings became unclean before they were sanctified in a vessel, they may be redeemed. If [they became unclean] after they were sanctified in a vessel, they may not be redeemed. Bird-offerings, the wood, the frankincense, and the ministering vessels, may not be redeemed, for the rule of redemption applies only to [offerings of] beasts.

If one said, “I take upon myself [to bring a minhah prepared] on a griddle”, and he brought one prepared in a pan, or “a minhah prepared in a pan”, and he brought one prepared on a griddle, what he has brought he has brought, but he has not fulfilled his obligation. [But if he said, “I take upon myself] to bring this [flour] as a minhah prepared on a griddle”, and he brought it prepared in a pan; or as “a minhah prepared in a pan”, and he brought it prepared on a griddle, it is invalid. If one said, “I take upon myself to bring two tenths in one vessel”, and he brought them in two vessels, or [he said] “in two vessels,” and he brought them in one vessel, what he has brought he has brought, but he has not fulfilled his obligation. But [if he said, “I take upon myself to bring] these [two tenths] in one vessel”, and he brought them in two vessels, or “in two vessels”, and he brought them in one vessel, they are invalid. If he said, “I take upon myself to bring two tenths in one vessel” and he brought them in two vessels, and when they said to him, “You vowed to bring them in one vessel”, if he brought them in one vessel, they are valid, but if he still offered them in two vessels, they are invalid. If he said “I take upon myself to bring two tenths in two vessels”, and he brought them in one vessel, and when they said to him, “You vowed to bring them in two vessels”, if he offered them in two vessels they are valid; but if he still kept them in one vessel, they are considered as two menahot which have been mixed.

[If one said,] “I take upon myself to bring a minhah of barley,” he must bring one of wheat. “Of coarse flour,” he must bring it of fine flour. “Without oil and without frankincense,” he must bring it with oil and frankincense. “Half a tenth,” he must bring a whole tenth. “A tenth and a half,” he must bring two. Rabbi Shimon declares him exempt, because he did not make his offering in the manner in which people usually make their offerings.

A man may offer a minhah consisting of sixty tenths and bring them in one vessel. If one said, “I take upon myself to offer sixty-one tenths,” he must bring sixty in one vessel and the one in another vessel, since the congregation brings on the first day of the festival [of Sukkot] when it falls on Shabbat sixty-one tenths [as a minhah], it is enough for an individual that [his minhah] should be one tenth less than that of the congregation. Rabbi Shimon said: but some of these [sixty-one tenths] are for the bullocks and some for the lambs, and they may not be mixed one with the other! Rather sixty tenths mingles [in one vessel]. They said to him: can sixty be mingled [in one vessel] and not sixty-one? He answered, so it is with all the measures prescribed by the sages: a man may immerse himself in forty seahs of water, but he may not immerse himself in forty seahs less one kortob. One may not offer one [log], two, or five [logs], but one may offer three, four, six, or anything above six.

One may offer wine but not oil, the words of Rabbi Akiva. But Rabbi Tarfon says: one may also offer oil. Rabbi Tarfon said: just as we find that wine is offered as an obligation may be offered as a freewill-offering, so oil which is offered as an obligation may be offered as a freewill-offering. Rabbi Akiva said to him: No, if you say so of wine it is because it is offered by itself even when offered as an obligation, can you say the same of oil which is not offered by itself when offered as an obligation? Two [men] may not jointly offer one tenth [of flour for a minhah]; but they may jointly offer an olah or a shelamim, and bird sacrifices even a single bird.
