Leviticus 22:18-20

18Speak unto Aaron, and to his sons, and unto all the children of Israel, and say unto them, Whatever man of the house of Israel, or of the sojourners in Israel, that presenteth his offering for any of his vows, and for any of his voluntary offerings, which they present to Jehovah as a burnt-offering,

19it shall be for your acceptance, without blemish, a male of the oxen, of the sheep, and of the goats.

20Nothing that hath a defect shall ye present; for it shall not be acceptable for you.
