Numbers 5:21-22

21(then the priest shall have the woman swear 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 waste away and your abdomen swell;

22and this water that brings a curse shall go into your stomach, and make your abdomen swell and your thigh waste away.” And the woman shall say, “Amen. Amen (so let it be).”
