Leviticus 22:21-24

21If a man presents a peace offering sacrifice to the Lord for a special votive offering or for a freewill offering from the herd or the flock, it must be flawless to be acceptable; it must have no flaw.

22“‘You must not present to the Lord something blind, or with a broken bone, or mutilated, or with a running sore, or with a festering eruption, or with a feverish rash. You must not give any of these as a gift on the altar to the Lord.

23As for an ox or a sheep with a limb too long or stunted, you may present it as a freewill offering, but it will not be acceptable for a votive offering.

24You must not present to the Lord something with testicles that are bruised, crushed, torn, or cut off; you must not do this in your land.
