Numbers 5:12-17

12“Speak to the sons of Israel and say to them, ‘If any man’s wife 1goes astray and is unfaithful to him, 13and a man has 2sexual relations with her and it is hidden from the eyes of her husband and she remains undiscovered, although she has defiled herself, and there is no witness against her and she has not been caught in the act, 143if 4an attitude of 5jealousy comes over him and he is jealous of his wife when she has defiled herself, or if 6an attitude of jealousy comes over him and he is jealous of his wife when she has not defiled herself, 15the man shall then bring his wife to the priest, and shall bring as 7an offering for her a tenth of an 8ephah of barley meal; he shall not pour oil on it nor put frankincense on it, because it is a grain offering of jealousy, a grain offering of reminder, 9a reminder of wrongdoing.

16‘Then the priest shall bring her forward and have her stand before the Lord, 17and the priest shall take holy water in an earthenware container; and 10he shall take some of the dust that is on the floor of the tabernacle and put it in the water.
