Numbers 5:11

7 and must confess the sin he has committed. He must make full restitution, add a fifth to its value, and give all this to the one he has wronged.

8 But if the man has no relative to whom restitution can be made for the wrong, the restitution belongs to the LORD and must be given to the priest along with the ram of atonement, by which the atonement is made for him.

9 Every sacred contribution the Israelites bring to the priest shall belong to him.

10 Each man’s sacred gifts are his own, but whatever he gives to the priest will belong to the priest.”

11 Then the LORD said to Moses,

12 “Speak to the Israelites and tell them that if any man’s wife goes astray and is unfaithful to him

13 by sleeping with another man, and it is concealed from her husband and her impurity is undetected (since there is no witness against her and she was not caught in the act),

14 and if a feeling of jealousy comes over her husband and he suspects his wife who has defiled herself—or if a feeling of jealousy comes over him and he suspects her even though she has not defiled herself—

15 then he is to bring his wife to the priest. He must also bring for her an offering of a tenth of an ephah of barley flour. He is not to pour oil over it or put frankincense on it, because it is a grain offering for jealousy, an offering of memorial as a reminder of iniquity.
