[If he said,] ‘‘I take upon myself [to bring] a minchah-offering from barley,’’ he must bring one from wheat. [If he said,] ‘‘coarse flour,’’ he must bring fine flour; ‘‘without oil and frankincense,’’ he must bring it with oil and frankincense; ‘‘half an issaron,’’ he must bring an issaron; ‘‘an issaron and a half,’’ he must bring two. R’ Shimon exempts [him] because he did not donate in the manner of those who donate.

A person may donate a minchah-offering of sixty issaron and bring [it] in one vessel. If he said, ‘‘I take upon myself [to bring] sixty-one [issaron],’’ he brings sixty in one vessel and one in another. For similarly the congregation brings sixty-one on the first day of Succos which falls on the Sabbath; it is sufficient for the individual that he be one less than the congregation. Said R’ Shimon: But aren’t these for the bulls and these for the lambs — and they may not be mixed with one another! Rather, until sixty they can be mixed. They said to him: ‘‘Sixty can be mixed and sixty-one cannot be mixed?’’ He said to them: All measurements of the Sages are thus; in forty seah one can immerse, [but] in forty seah less one kortov he cannot immerse. One cannot donate a log, two [lugin], or five; but he can donate three, four, or six, and from six and up.

One can donate wine, but one cannot donate oil; [these are] the words of R’ Akiva. R’ Tarfon says: One can donate oil. Said R’ Tarfon: Just as we find concerning wine that it comes as an obligation or as a donation, so too, oil comes as an obligation or as a donation. R’ Akiva said to him: No. If this is said of wine, it is because it is brought as an obligation on its own. Can you say [the same] of oil which is not brought as an obligation on its own? Two [people] cannot donate one issaron, but they can donate an olah-offering and a shelamim-offering, and with a bird, even a single bird.

[If one said,] ‘‘I take upon myself [to bring] an issaron’’ — he brings one; [if he said,] ‘‘essronim’’ — he brings two. [If he said,] ‘‘I specified, but I do not know what I specified’’ — he must bring sixty issaron. [If he said,] ‘‘I take upon myself [to bring] a minchahoffering’’ — he may bring whichever he wishes. R’ Yehudah says: He must bring the minchah of fine flour, for that is the principal minchah-offering.
