Lev 19:6-8

6It shall be eaten on the same day you offer it, or on the next day; and anything left over until the third day shall be consumed in fire.7If it is eaten at all on the third day, it is an abomination; it will not be acceptable.8All who eat it shall be subject to punishment, because they have profaned what is holy to the Lord; and any such person shall be cut off from the people.
