Leviticus 22:18-23

“Speak to Aaron, his sons, and all the Israelites and tell them: Any man of the house of Israel or of the resident aliens  in Israel who presents his offering   — whether they present payment of vows or freewill gifts to the LORD as burnt offerings —  must offer an unblemished male  from the cattle, sheep, or goats in order for you to be accepted. You are not to present anything that has a defect, because it will not be accepted on your behalf. “When a man presents a fellowship sacrifice to the LORD to fulfill a vow or as a freewill offering from the herd or flock, it has to be unblemished to be acceptable; there must be no defect in it. You are not to present any animal to the LORD that is blind, injured, maimed, or has a running sore, festering rash,  or scabs; you may not put any of them on the altar as a food offering to the LORD.  You may sacrifice as a freewill offering any animal from the herd or flock that has an elongated or stunted limb, but it is not acceptable as a vow offering.
