Leviticus 18:6-10

⁶None of you shall approach to any that are near of kin to him, to uncover their nakedness: I am the Lord.

⁷The nakedness of thy father, or the nakedness of thy mother, shalt thou not uncover: she is thy mother, thou shalt not uncover her nakedness.

⁸The nakedness of thy father's wife shalt thou not uncover: it is thy father's nakedness.

⁹The nakedness of thy sister, the daughter of thy father, or the daughter of thy mother, whether she be born at home, or born abroad,—even the nakedness of any of these shalt thou not uncover.

¹⁰The nakedness of thy son's daughter, or of thy daughter's daughter,—even the nakedness of any of these, shalt thou not uncover; for theirs is thy own nakedness.
