Leviticus 22:18-23

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,

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

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

21When 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.

22Do not offer to the Lord the blind, the injured or the maimed, or anything with warts or festering or running sores. Do not place any of these on the altar as a food offering presented to the Lord.

23You may, however, present as a freewill offering an ox or a sheep that is deformed or stunted, but it will not be accepted in fulfillment of a vow.
