Leviticus 22:14-16

Amplified Bible

¹⁴ But if a person unknowingly eats a holy gift [which has been offered to God], then he shall add one-fifth of its value to it and give the holy gift to the priest. ¹⁵ The priests shall not profane the holy things the Israelites offer to the Lord, ¹⁶ and so cause them [by neglect of any essential observance] to bear the ^[a]punishment of guilt when they eat their holy things; for I am the Lord who sanctifies them.’”
