Leviticus 22:19-21

22:19 if it is to be acceptable for your benefit it must be a flawless male from the cattle, sheep, or goats. 22:20 You must not present anything that has a flaw, because it will not be acceptable for your benefit. 22:21 If a man presents a peace offering sacrifice to the Lord for a special votive offering or for a freewill offering from the herd or the flock, it must be flawless to be acceptable; it must have no flaw.
