Leviticus 22:14-16

141If, however, someone eats a holy food unintentionally, then he shall add to it a fifth of it and shall give the holy food to the priest. 15And 2they shall not profane the holy gifts of the sons of Israel, which they offer to the Lord, 16and thereby 3bring upon them 4punishment for guilt by eating their holy gifts; for I am the Lord who sanctifies them.’”
