KJV:
And this water that causeth the curse shall go into thy bowels, to make thy belly to swell, and thy thigh to rot: And the woman shall say, Amen, amen.
NASB:
and 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."
KJV:
And when he hath made her to drink the water, then it shall come to pass, that, if she be defiled, and have done trespass against her husband, that the water that causeth the curse shall enter into her, and become bitter, and her belly shall swell, and her thigh shall rot: and the woman shall be a curse among her people.
NASB:
When he has made her drink the water, then it shall come about, if she has defiled herself and has been unfaithful to her husband, that the water which brings a curse will go into her and cause bitterness, and her abdomen will swell and her thigh will waste away, and the woman will become a curse among her people.
