Leviticus 19:4-6

⁴Ye shall not turn unto the idols, and molten gods shall ye not make to yourselves: I am the Lord your God.

⁵And if ye offer a sacrifice of peace-offering unto the Lord, ye shall offer it so that it may be favorably received from you.

⁶On the same day ye offer it shall it be eaten, and on the morrow: and whatever is left until the third day, shall be burnt with fire.
