Leviticus 19:5

3Ye shall fear every man his mother, and his father, and keep my sabbaths: I am the LORD your God.

4Turn ye not unto idols, nor make to yourselves molten gods: I am the LORD your God.

5And if ye offer a sacrifice of peace offerings unto the LORD, ye shall offer it at your own will.

6It 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.

7And if it be eaten at all on the third day, it is abominable; it shall not be accepted.
