Numbers 5:11-19

11Then the Lord said to Moses,

12“Speak to the Israelites and say to them: ‘If a man’s wife goes astray and is unfaithful to him

13so that another man has sexual relations with her, and this is hidden from her husband and her impurity is undetected (since there is no witness against her and she has not been caught in the act),

14and if feelings of jealousy come over her husband and he suspects his wife and she is impure—or if he is jealous and suspects her even though she is not impure—

15then he is to take his wife to the priest. He must also take an offering of a tenth of an ephah of barley flour on her behalf. He must not pour olive oil on it or put incense on it, because it is a grain offering for jealousy, a reminder-offering to draw attention to wrongdoing.

16“ ‘The priest shall bring her and have her stand before the Lord.

17Then he shall take some holy water in a clay jar and put some dust from the tabernacle floor into the water.

18After the priest has had the woman stand before the Lord, he shall loosen her hair and place in her hands the reminder-offering, the grain offering for jealousy, while he himself holds the bitter water that brings a curse.

19Then the priest shall put the woman under oath and say to her, “If no other man has had sexual relations with you and you have not gone astray and become impure while married to your husband, may this bitter water that brings a curse not harm you.
