Leviticus 18:11 (KJV)

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

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

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

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

The nakedness of thy son's daughter, or of thy daughter's daughter, even their nakedness thou shalt not uncover: for theirs is thine own nakedness.

Thou shalt not uncover the nakedness of thy father's sister: she is thy father's near kinswoman.

Thou shalt not uncover the nakedness of thy mother's sister: for she is thy mother's near kinswoman.

Thou shalt not uncover the nakedness of thy father's brother, thou shalt not approach to his wife: she is thine aunt.

Thou shalt not uncover the nakedness of thy daughter in law: she is thy son's wife; thou shalt not uncover her nakedness.

Thou shalt not uncover the nakedness of thy brother's wife: it is thy brother's nakedness.
