Leviticus 22:20-25

20Do not bring anything with a defect, because it will not be accepted on your behalf. 21When anyone brings from the herd or flock a fellowship offering to the LORD to fulfill a special vow or as a freewill offering, it must be without defect or blemish to be acceptable. 22Do 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 . 23You may, however, present as a freewill offering an ox The Hebrew word can refer to either male or female. or a sheep that is deformed or stunted, but it will not be accepted in fulfillment of a vow. 24You 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,

25and 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.’ ”
