Leviticus 22:14-16

141But if a man eats a holy gift unintentionally, then he shall add to it a fifth of it and shall give the holy gift to the priest. 152They shall not profane the holy gifts of the sons of Israel which they offer to the Lord, 16and so cause them 3to bear 4punishment for guilt by eating their holy gifts; for I am the Lord who sanctifies them.’”
