Leviticus 22:21-24

21Whoever brings a sacrifice of fellowship offerings to Adonai to fulfill a vow or for a freewill offering, either from the herd or the flock, it must be unblemished to be accepted—there must be no defect on it.

22The blind, injured, maimed, having an abnormal growth or festering or a running sore are not to be offered to Adonai, or given as an offering by fire on the altar to Adonai.

23For a freewill offering you may present a bull or a lamb that has any deformity or lacking in its parts, but for a vow it will not be accepted.

24Whatever has its testicles bruised, crushed, broken or cut, you are not to offer to Adonai, nor are you to do so in your own land.
