Leviticus 22:18-20

18“Speak to Aaron and his sons, and to all the children of Israel, and say to them: ‘Whatever man of the house of Israel, or of the strangers in Israel, who offers his sacrifice for any of his vows or for any of his freewill offerings, which they offer to the Lord as a burnt offering—

19you shall offer of your own free will a male without blemish from the cattle, from the sheep, or from the goats.

20Whatever has a defect, you shall not offer, for it shall not be acceptable on your behalf.
