Leviticus 22:20-24

20Never bring any animal with a physical defect, because it will not be accepted on your behalf.

21A person may bring the Lord a fellowship offering to fulfill a vow or for a freewill offering. Whether it is from the cattle, sheep, or goats, it must be an animal that has no defects in order to be accepted. It must never be an animal that has defects.

22Never bring the Lord an animal that is blind, has broken bones, cuts, warts, scabs, or ringworm. Never give the Lord any of these in a sacrifice by fire on the altar.

23You may use a bull or a sheep with a deformity or one that is stunted in growth as a freewill offering. However, it will not be accepted for a vow.

24Never bring the Lord an animal that has bruised, crushed, torn out, or cut out testicles. Never do any of these things to an animal in your land.
