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.
— Leviticus 22:18-21
