Numbers 5:19-24

19Then the priest shall make her take an oath, saying, 'If no man has lain with you, and if you have not turned aside to uncleanness while you were under your husband's authority, be free from this water of bitterness that brings the curse.

20But if you have gone astray, though you are under your husband's authority, and if you have defiled yourself, and some man other than your husband has lain with you,

21then' (let the priest make the woman take 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 fall away and your body swell.

22May this water that brings the curse pass into your bowels and make your womb swell and your thigh fall away.' And the woman shall say, 'Amen, Amen.'

23"Then the priest shall write these curses in a book and wash them off into the water of bitterness.

24And he shall make the woman drink the water of bitterness that brings the curse, and the water that brings the curse shall enter into her and cause bitter pain.
