Numbers 5:24

20But if you have gone astray, being under your husband’s authority, and if you are defiled, and some man has lain with you besides your husband—”

21then the priest shall cause the woman to swear with the oath of cursing, and the priest shall tell the woman, “May the LORD make you a curse and an oath among your people, when the LORD allows your thigh to fall away, and your body to swell;

22and this water that brings a curse will go into your bowels, and make your body swell, and your thigh fall away.” The woman shall say, “Amen, Amen.”

23“‘The priest shall write these curses in a book, and he shall wipe them into the water of bitterness.

24He shall make the woman drink the water of bitterness that causes the curse; and the water that causes the curse shall enter into her and become bitter.

25The priest shall take the meal offering of jealousy out of the woman’s hand, and shall wave the meal offering before the LORD, and bring it to the altar.

26The priest shall take a handful of the meal offering, as its memorial portion, and burn it on the altar, and afterward shall make the woman drink the water.

27When he has made her drink the water, then it shall happen, if she is defiled and has committed a trespass against her husband, that the water that causes the curse will enter into her and become bitter, and her body will swell, and her thigh will fall away; and the woman will be a curse among her people.

28If the woman isn’t defiled, but is clean; then she shall be free, and shall conceive offspring.
