Leviticus 22:19-21

¹⁹Ye shall offer at your own will a male without blemish, of the beeves, of the sheep, or of the goats.

²⁰But whatsoever hath a blemish, that shall ye not offer: for it shall not be acceptable for you.

²¹And whosoever offereth a sacrifice of peace offerings unto the LORD to accomplish his vow, or a freewill offering in beeves or sheep, it shall be perfect to be accepted; there shall be no blemish therein.
