Numbers 5
18 Ref The priest shall set the woman before Yahweh, and let the hair of the woman's head go loose, and put the meal offering of memorial in her hands, which is the meal offering of jealousy. The priest shall have in his hand the water of bitterness that brings a curse.
19 Ref The priest shall cause her to swear, and shall tell the woman, 'If no man has lain with you, and if you haven't gone aside to uncleanness, being under your husband, be free from this water of bitterness that brings a curse.
20 Ref But if you have gone astray, being under your husband, and if you are defiled, and some man has lain with you besides your husband:'
21 Ref then the priest shall cause the woman to swear with the oath of cursing, and the priest shall tell the woman, 'Yahweh make you a curse and an oath among your people, when Yahweh allows your thigh to fall away, and your body to swell;
22 Ref and 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 Ref "The priest shall write these curses in a book, and he shall blot them out into the water of bitterness.
24 Ref He 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.
