Leviticus 22:21-22

²¹And if a man present a consecrated victim before the Lord, as a vow set apart, or a free-will offering of the herd or of the flock, it must be perfect, to be acceptable; there shall be no blemish in it.

²²Blind, or broken, or mutilated, or having imposthumes, or ulcers, or blotches, these you shall not offer before the Lord, nor of them present an oblation upon the altar before the Lord.
