Leviticus 22:17-20

17Then the LORD said to Moses, 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.
