Numbers 5:23-31

23“ ‘The priest is to write these curses on a scroll and then wash them off into the bitter water. 24He shall make the woman drink the bitter water that brings a curse, and this water that brings a curse and causes bitter suffering will enter her. 25The priest is to take from her hands the grain offering for jealousy, wave it before the LORD and bring it to the altar. 26The priest is then to take a handful of the grain offering as a memorial Or representative offering and burn it on the altar; after that, he is to have the woman drink the water. 27If she has made herself impure and been unfaithful to her husband, this will be the result: When she is made to drink the water that brings a curse and causes bitter suffering, it will enter her, her abdomen will swell and her womb will miscarry, and she will become a curse.

28If, however, the woman has not made herself impure, but is clean, she will be cleared of guilt and will be able to have children. 29“ ‘This, then, is the law of jealousy when a woman goes astray and makes herself impure while married to her husband, 30or when feelings of jealousy come over a man because he suspects his wife. The priest is to have her stand before the LORD and is to apply this entire law to her. 31The husband will be innocent of any wrongdoing, but the woman will bear the consequences of her sin.’ ”
