Numbers 5:12-17

12“Speak to the Israelites and tell them, ‘If any man’s wife goes astray and behaves unfaithfully toward him,

13and a man has sexual relations with her without her husband knowing it, and it is hidden that she has defiled herself, since there was no witness against her, nor was she caught –

14and if jealous feelings come over him and he becomes suspicious of his wife, when she is defiled; or if jealous feelings come over him and he becomes suspicious of his wife, when she is not defiled –

15then the man must bring his wife to the priest, and he must bring the offering required for her, one tenth of an ephah of barley meal; he must not pour olive oil on it or put frankincense on it, because it is a grain offering of suspicion, a grain offering for remembering, for bringing iniquity to remembrance.

16“‘Then the priest will bring her near and have her stand before the Lord.

17The priest will then take holy water in a pottery jar, and take some of the dust that is on the floor of the tabernacle, and put it into the water.
