Leviticus 22:22-25

Do not offer to the LORD the blind, the injured or the maimed, or anything with warts or festering or running sores. Do not place any of these on the altar as a food offering presented to the LORD. You may, however, present as a freewill offering an ox or a sheep that is deformed or stunted, but it will not be accepted in fulfillment of a vow. You must not offer to the LORD an animal whose testicles are bruised, crushed, torn or cut. You must not do this in your own land, and you must not accept such animals from the hand of a foreigner and offer them as the food of your God. They will not be accepted on your behalf, because they are deformed and have defects.’ ”
