Numbers 5:11-19

11Adonai spoke to Moses saying,

12“Speak to Bnei-Yisrael and say to them: Suppose some man’s wife goes astray and is unfaithful to him,

13and another man has sexual relations with her, but it is hidden from her husband’s eyes and her impurity is not detected. Yet there was no witness against her and she was not caught in the act.

14Then a spirit of jealousy overcomes him and he is suspicious of his wife, when she is impure. Or a spirit of jealousy overcomes him and he suspects his wife, yet she is not impure.

15“Then he should take his wife to the kohen. He must also bring a tenth of an ephah of barley flour as an offering for her. He is not to pour oil or put incense on it, because it is an offering for jealousy, a reminder offering drawing attention to guiltiness.

16“The kohen is to bring her near and have her stand before Adonai.

17Then the kohen is to take some holy water in a clay jar and take some dust from the floor of the Tabernacle and put it into the water.

18Then the kohen will have the woman stand before Adonai, loosen the woman’s hair, put into her hands the reminder offering, the offering for jealousy, while in the kohen’s own hands are the bitter waters that bring a curse.

19Then the kohen will have her swear under oath, then say to the woman, ‘If no man other than your husband has slept with you, and if you have not gone astray into impurity from your husband, may this bitter water that brings a curse not harm you.
