'Abdomen' in the Bible

Then 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;

and 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."

When he has made her drink the water, then, if she has defiled herself and behaved unfaithfully toward her husband, the water that brings a curse will enter her to produce bitterness -- her abdomen will swell, her thigh will fall away, and the woman will become a curse among her people.

and went after the Israelite man into the tent and thrust through the Israelite man and into the woman's abdomen. So the plague was stopped from the Israelites.
