Leviticus 22:14-16 ▼

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 punishment of guilt when they eat their holy things; for I am the LORD who sanctifies them.’”
