G‑d communicates to Moses the law of the sotah, the wayward wife suspected of unfaithfulness to her husband.

Burning the Challah Portion

Once you intend a particular piece of dough to be the challa portion, you must burn that piece and not put it back into the main dough.

There is no time limit for burning “challa.” You may save several pieces for burning together, but you may not keep them in a place where they might get used.

You may burn the challa portion any way you wish.  You must burn it completely.
