Leviticus 22:18-21

Thomson(i) 18 Speak to Aaron and his sons, and to the whole congregation of Israel, and thou shalt say unto them, Be the man who he may of the children of Israel, or of the proselytes who dwell among them in Israel, who shall bring his gifts according to any vow they may have made, or according to any determination they may have come to, whatever they bring for a whole burnt offering to God, 19 must, in order to be accepted for you, be males without blemish, from the herd, or from the sheep, or from the goats. 20 What hath any blemish in it they shall not bring to the Lord; for it will not be accepted for you. 21 And whoever shall bring a sacrifice of thanksgiving to the Lord, either in discharge of a vow, or as a free will offering, or at your festivals, from the herd or from the flock, it must, in order to its being accepted, be without blemish. There must be no blemish in it.
