Yose ben Choni says: [Sacrifices] slaughtered for the pesach designation or the chatas designation are invalid. Shimon the brother of Azaryah says: [If] they were slaughtered for a designation higher than their own, they are valid; for a designation lower than their own, they are invalid. How so? Most holy offerings which he slaughtered for an offering of lesser holiness designation are invalid; offerings of lesser holiness which he slaughtered for a most holy offering designation are valid. The bechor- and the maaser-offerings which were slaughtered for the shelamim designation are valid, and shelamim-offerings which he slaughtered for the bechor [or] the maaser designation are invalid.

A pesach-offering which was slaughtered on the morning of the fourteenth [of Nissan] for a designation other than its own — R’ Yehoshua validates [it] as if it had been slaughtered on the thirteenth; [but] Ben Beseira invalidates [it] as if it had been slaughtered in the afternoon. Said Shimon ben Azai: I have received a tradition from the seventy-two Sages, on the day that they appointed R’ Elazar ben Azaryah to the Yeshivah, that all sacrifices that are eaten, which were slaughtered for a designation other than their own, are valid; but they are not credited to the owner as fulfillment of his obligation; except for the pesach- and chatas-offerings. Ben Azai added only the olah offering, but the Sages did not concur with him.
