Numbers 5:19-24

19The priest will require the woman to take an oath and will say to her, ‘If no man has slept with you, if you have not gone astray and become defiled while under your husband’s authority, be unaffected by this bitter water that brings a curse.

20But if you have gone astray while under your husband’s authority, if you have defiled yourself and a man other than your husband has slept with you’ —

21at this point the priest will make the woman take the oath with the sworn curse, and he is to say to her — ‘May the Lord make you into an object of your people’s cursing and swearing when he makes your womb shrivel and your belly swell.

22May this water that brings a curse enter your stomach, causing your belly to swell and your womb to shrivel.’ “And the woman will reply, ‘Amen, Amen.’

23“Then the priest is to write these curses on a scroll and wash them off into the bitter water.

24He will require the woman to drink the bitter water that brings a curse, and it will enter her to cause bitter suffering.
