Leviticus 22:22-25

Animals 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. You 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. Any 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, neither 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.”
