Numbers 5:22 WEB

²⁰  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  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  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  'The priest shall write these curses in a book, and he shall blot them out into the water of bitterness.

²⁴  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.
