Leviticus 22:20-24

Whatever has a defect, you shall not offer, for it will not be accepted for you.

When someone offers a sacrifice of peace offerings to the Lord to fulfill a special vow or for a voluntary offering, of the herd or of the flock, it must be without defect to be accepted; there shall be no defect in it.

Those that are blind, fractured, maimed, or have a wart, a festering rash, or scabs, you shall not offer to the Lord, nor make of them an offering by fire on the altar to the Lord.

Now as for an ox or a lamb which has an overgrown or stunted member, you may present it as a voluntary offering, but for a vow it will not be accepted.

Also anything with its testicles squashed, crushed, torn off, or cut off, you shall not offer to the Lord, nor sacrifice in your land,
