Leviticus 20:19-21

21st Century King James Version

¹⁹ And thou shalt not uncover the nakedness of thy mother’s sister nor of thy father’s sister, for he uncovereth his near kin: they shall bear their iniquity.

²⁰ And if a man shall lie with his uncle’s wife, he hath uncovered his uncle’s nakedness. They shall bear their sin: they shall die childless.

²¹ And if a man shall take his brother’s wife, it is an unclean thing. He hath uncovered his brother’s nakedness: they shall be childless.
