Leviticus 18:15-20

¹⁵You shall not uncover the nakedness of your daughter-in-law, for she is your son's wife, you shall not uncover her nakedness.

¹⁶You shall not uncover the nakedness of your brother's wife: it is your brother's nakedness.

¹⁷The nakedness of a woman and her daughter shall you not uncover; her son's daughter, and her daughter's daughter, shall you not take, to uncover their nakedness, for they are your kinswomen: it is impiety.

¹⁸You shall not take a wife in addition to her sister, as a rival, to uncover her nakedness in opposition to her, while she is yet living.

¹⁹And you shall not go in to a woman under separation for her uncleanness, to uncover her nakedness.

²⁰And you shall not lie with your neighbor's wife, to defile yourself with her.
