Beraisa #1: Before the time of bi'ur arrives, one may destroy it in any way. Once the time of bi'ur arrives (that it becomes obligatory to destroy it), it must be destroyed through burning. This follows the opinion of R' Yehudah.

Beraisa #2: Before the time of bi'ur arrives, one must destroy it through burning. Once the time of bi'ur has arrived, one may destroy it in any way (rather than be limited in the way one may burn it, thereby possibly causing someone not to destroy it (see earlier 25-2(b)). This follows the opinion of Rabanan (Chachamim).

Beraisa (Rebbi): "Destroy Se'or from your houses'' - in a way that prevents Bal Yera'eh and bal yematzei (the Chametz being visible/found) - this is achieved through burning.

Query (R' Yirmiyah): If a firstborn donkey killed a person, how is it put to death - by breaking its neck or by stoning? (Any other animal that killed a person is stoned. On the other hand, if the owner of a firstborn donkey does not wish to redeem it, its neck is broken. It is unclear which of these deaths should be applied to the donkey that killed - should it be treated with the more stringent death of stoning because of the act that it did?)

Query (R' Binyamin bar Levi): (According to the Rabanan) Loaves of a Todah offering that became nosar (they were not eaten before their prescribed time limit)(How are they destroyed on Erev Pesach after the time of bi'ur - through burning like all other nosar, or in any way like all other Chametz?)

Answer: If it became nosar before the time of bi'ur (that the mitzvah of burning nosar had already come), it is destroyed through burning; if it was after the time of bi'ur (that the mitzvah of destroying had already come), it is destroyed in any way. (Note: This sentence follows the text of the Korban ha'Edah).
