Leviticus 7:15-19

7:15 The meat of his thanksgiving peace offering must be eaten on the day of his offering; he must not set any of it aside until morning.

7:16 “‘If his offering is a votive or freewill sacrifice, it may be eaten on the day he presents his sacrifice, and also the leftovers from it may be eaten on the next day, 7:17 but the leftovers from the meat of the sacrifice must be burned up in the fire on the third day. 7:18 If some of the meat of his peace offering sacrifice is ever eaten on the third day it will not be accepted; it will not be accounted to the one who presented it, since it is spoiled, and the person who eats from it will bear his punishment for iniquity. 7:19 The meat which touches anything ceremonially unclean must not be eaten; it must be burned up in the fire. As for ceremonially clean meat, everyone who is ceremonially clean may eat the meat.
