Leviticus 22:19-23

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

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

And 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.

Blind, or broken, or maimed, or having a wen, or scurvy, or scabbed, ye shall not offer these unto the LORD, nor make an offering by fire of them upon the altar unto the LORD.

Either a bullock or a lamb that hath any thing superfluous or lacking in his parts, that mayest thou offer for a freewill offering; but for a vow it shall not be accepted.
