Leviticus 22:16-21 New International Version (NIV)

16. by allowing them to eat the sacred offerings and so bring upon them guilt requiring payment. I am the Lord, who makes them holy.’ ”

17. The Lord said to Moses,

18. “Speak to Aaron and his sons and to all the Israelites and say to them: ‘If any of you—whether an Israelite or a foreigner residing in Israel—presents a gift for a burnt offering to the Lord, either to fulfill a vow or as a freewill offering,

19. you must present a male without defect from the cattle, sheep or goats in order that it may be accepted on your behalf.

20. Do not bring anything with a defect, because it will not be accepted on your behalf.

21. When anyone brings from the herd or flock a fellowship offering to the Lord to fulfill a special vow or as a freewill offering, it must be without defect or blemish to be acceptable.
