Leviticus 19:6

It shall be eaten the same day ye offer it, and on the morrow: and if ought remain until the third day, it shall be burnt in the fire.
4

Turn ye not unto idols, nor make to yourselves molten gods: I am the Lord your God.

5

And if ye offer a sacrifice of peace offerings unto the Lord, ye shall offer it at your own will.

6

It shall be eaten the same day ye offer it, and on the morrow: and if ought remain until the third day, it shall be burnt in the fire.

7

And if it be eaten at all on the third day, it is abominable; it shall not be accepted.

8

Therefore every one that eateth it shall bear his iniquity, because he hath profaned the hallowed thing of the Lord: and that soul shall be cut off from among his people.
