King James Version
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.English Standard Version
And when he has made her drink the water, then, if she has defiled herself and has broken faith with her husband, the water that brings the curse shall enter into her and cause bitter pain, and her womb shall swell, and her thigh shall fall away, and the woman shall become a curse among her people.New International Version
If she has defiled herself and been unfaithful to her husband, then when she is made to drink the water that brings a curse, it will go into her and cause bitter suffering; her abdomen will swell and her thigh waste away, and she will become accursed among her people.
