Leviticus 22:18

15 They shall not profane the holy things of the children of Israel, which they offer to Yahweh,

16 and [so] cause them to bear the iniquity that brings guilt, when they eat their holy things: for I am Yahweh who sanctifies them.

17 Yahweh spoke to Moses, saying,

18 Speak to Aaron, and to his sons, and to all the children of Israel, and tell them, Whoever he be of the house of Israel, or of the sojourners in Israel, that offers his offering, whether it be any of their vows, or any of their freewill-offerings, which they offer to Yahweh for a burnt offering;

19 that you may be accepted, [you shall offer] a male without blemish, of the bulls, of the sheep, or of the goats.

20 But whatever has a blemish, that shall you not offer: for it shall not be acceptable for you.

21 Whoever offers a sacrifice of peace-offerings to Yahweh to accomplish a vow, or for a freewill-offering, of the herd or of the flock, it shall be perfect to be accepted; there shall be no blemish therein.
