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.
