Leviticus 22:19-25

19if it is to be accepted for you it shall be a male without blemish, of the bulls or the sheep or the goats. 20You shall not offer anything that has a blemish, for it will not be acceptable for you. 21And when anyone offers a sacrifice of peace offerings to the LORD to fulfill a vow or as a freewill offering from the herd or from the flock, to be accepted it must be perfect; there shall be no blemish in it. 22Animals blind or disabled or mutilated or having a discharge or an itch or scabs you shall not offer to the LORD or give them to the LORD as a food offering on the altar. 23You may present a bull or a lamb that has a part too long or too short for a freewill offering, but for a vow offering it cannot be accepted. 24Any animal that has its testicles bruised or crushed or torn or cut you shall not offer to the LORD; you shall not do it within your land, 25neither shall you offer as the bread of your God any such animals gotten from a foreigner. Since there is a blemish in them, because of their mutilation, they will not be accepted for you.”
