Leviticus 22:18-23

18“Speak to Aaron and his sons and all the Israelites and tell them, ‘Any man of the house of Israel or any foreign resident who presents a gift for a burnt offering to the LORD, whether to fulfill a vow or as a freewill offering, 19must offer an unblemished male from the cattle, sheep, or goats in order for it to be accepted on your behalf. 20You must not present anything with a defect, because it will not be accepted on your behalf.

21When a man presents a peace offering to the LORD from the herd or flock to fulfill a vow or as a freewill offering, it must be without blemish or defect to be acceptable. 22You are not to present to the LORD any animal that is blind, injured, or maimed, or anything with a running sore, a festering rash, or a scab; you must not put any of these on the altar as a food offering to the LORD.

23You may present as a freewill offering an ox1 or sheep that has a deformed or stunted limb, but it is not acceptable in fulfillment of a vow.
