NET

27 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.

Darby

27 And when he hath made her to drink the water, then it shall come to pass, if she have been defiled, and have committed unfaithfulness against her husband, that the water that bringeth the curse shall enter into her, for bitterness, and her belly shall swell, and her thigh shall shrink; and the woman shall become a curse among her people.

KJV

27 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.
