Leviticus 19:4-6

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.
