'Sister' in the Bible
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 father's wife's daughter, begotten of thy father, she is thy sister, thou shalt not uncover her 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.
Neither shalt thou take a wife to her sister, to vex her, to uncover her nakedness, beside the other in her life time.
And if a man shall take his sister, his father's daughter, or his mother's daughter, and see her nakedness, and she see his nakedness; it is a wicked thing; and they shall be cut off in the sight of their people: he hath uncovered his sister's nakedness; he shall bear his iniquity.
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.
