Numbers 5:21-22

21Then the priest will put the woman under the oath of the curse and will say to the her, “The Lord make you an attested curse among your people, if the Lord makes your thigh fall away and your abdomen swell;

22and this water that causes the curse will go into your stomach, and make your abdomen swell and your thigh rot.” Then the woman must say, “Amen, amen.”
