Leviticus 22:15-19
English Standard Version
Chapter 22
15They shall not profane the holy things of the people of Israel, which they contribute to the Lord, 16and so cause them to bear iniquity and guilt, by eating their holy things: for I am the Lord who sanctifies them."
17And the Lord spoke to Moses, saying,
18"Speak to Aaron and his sons and all the people of Israel and say to them, When any one of the house of Israel or of the sojourners in Israel presents a burnt offering as his offering, for any of their vows or freewill offerings that they offer to the Lord,
19if it is to be accepted for you it shall be a male without blemish, of the bulls or the sheep or the goats.
