Leviticus 22:19-21

MKJV(i) 19 you shall offer at your own will a male without blemish, of the cattle, of the sheep, or of the goats. 20 You shall not offer that which has a blemish. For it shall not be acceptable for you. 21 And when a man offers a sacrifice of peace offerings to Jehovah to carry out his vow, or a free-will offering in cattle or sheep, it shall be without blemish to be accepted. There shall be no blemish in them.
