Leviticus 19:5-7

New American Standard Bible

⁵ ‘Now when you offer a sacrifice of peace offerings to the Lord, you shall offer it so that you may be accepted. ⁶ It shall be eaten on the same day you offer it, and on the next day; but what remains until the third day shall be burned with fire. ⁷ So if it is eaten at all on the third day, it is unclean; it will not be accepted.
