Leviticus 22:18-19

“Tell Aaron and his sons and all the people of Israel: ‘A citizen of Israel or a foreigner living in Israel might want to bring a whole burnt offering, either for some special promise he has made or for a special gift he wants to give to the LORD. If he does, he must bring a male animal that has nothing wrong with it—a bull, a sheep, or a goat—so it might be accepted for him.
