Vayikra 20:19-21

Orthodox Jewish Bible

¹⁹ And thou shalt not uncover the nakedness of thy mother’s achot (sister), nor of thy father’s achot (sister); for he uncovereth (i.e., incestuously dishonored) his near kin; they shall bear their iniquity.

²⁰ And if an ish shall lie with the wife of his dod, he hath uncovered his uncle’s nakedness; they shall bear their chet; they shall die childless.

²¹ And if an ish shall take his brother’s wife, it is niddah; he hath uncovered his brother’s nakedness; they shall be childless.
