Numbers 5:18-27

18The priest shall then have the woman stand before the Lord, and let the hair of the woman’s head hang loose, and put the memorial grain offering in her hands, which is the jealousy offering, and in the hand of the priest is to be the water of bitterness that brings a curse.

19Then the priest shall have her take an oath and say to the woman, “If no man has lain with you and if you have not gone astray into uncleanness [while married], then be immune to this water of bitterness that brings a curse;

20but if you have gone astray [while married] and you have defiled yourself and a man other than your husband has been intimate with you”

21(then the priest shall have the woman swear the oath of the curse, and say to the woman), “The Lord make you a curse and an oath among your people when the Lord makes your thigh waste away and your abdomen swell;

22and this water that brings a curse shall go into your stomach, and make your abdomen swell and your thigh waste away.” And the woman shall say, “Amen. Amen (so let it be).”

23‘The priest shall then write these curses on a scroll and shall wash them off into the water of bitterness;

24and he shall make the woman drink the water of bitterness that brings a curse, and the water that brings the curse will go into her and cause bitterness.

25Then the priest shall take the grain offering of jealousy out of the woman’s hand, and he shall wave the grain offering before the Lord and offer it on the altar.

26Then the priest shall take a handful of the grain offering as the memorial portion of it and offer it up in smoke on the altar, and afterward he shall make the woman drink the water.

27When he has made her drink the water, then it shall come about, that if she has defiled herself and has been unfaithful to her husband, the curse water will go into her and cause bitterness and cause her abdomen to swell and her thigh to waste away, and the woman will become a curse among her people.
