R’ Shimon says: There are three types [of offerings], which [between them] require three procedures: two for each one, but not the third. They are: the individual’s shelamim-offerings, communal shelamim-offerings, and the asham-offering of the metzora. The individual’s shelamim-offerings require leaning while living and waving when slaughtered — but they do not require waving while living. Communal shelamim-offerings require waving while living and when slaughtered — but they do not require leaning. The asham-offering of the metzora requires leaning and waving while living — but it does not require waving when slaughtered.

[If] one said, ‘‘I take upon myself [to bring] in an oven,’’ he may not bring something baked in a small stove, [nor] one baked on tiles, [nor] one baked in an Arabian cauldron. R’ Yehudah says: If he wishes, he may bring that which is baked in a small stove. [If he said,] ‘‘I take upon myself [to bring] a baked minchah-offering,’’ he may not bring half as challos and half as rekikin. R’ Shimon permits [this] because it is one offering.
