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.
BSB
When he has made her drink the water, if she has defiled herself and been unfaithful to her husband, then the water that brings a curse will enter her and cause bitter suffering; her belly will swell, her thigh will shrivel, and she will become accursed among her people.
