Leviticus 7:16-18

Living Bible

¹⁶ “However, if someone brings a sacrifice that is not for thanksgiving, but is because of a vow or is simply a voluntary offering to the Lord, any portion of the sacrifice that is not eaten the day it is sacrificed may be eaten the next day. ^17-18 But anything left over until the third day shall be burned. For if any of it is eaten on the third day, the Lord will not accept it; it will have no value as a sacrifice, and there will be no credit to the one who brought it to be offered; and the priest who eats it shall be guilty, for it is detestable to the Lord, and the person who eats it must answer for his sin.
