'Sister' in the Bible

[As for] the nakedness of the daughter of your father's wife, she [is] your sister, a relative of your father; you must not expose her nakedness.

You must not expose the nakedness of your father's sister; she [is] {your father's close relative}.

You must not expose the nakedness of your mother's sister, because she [is] {your mother's close relative}.

And you must not take [as wife] a woman with her sister, to be a rival-wife, to expose her nakedness before her {during} her life.

" 'As for a man who takes his sister, his father's daughter or his mother's daughter, and he sees her nakedness and she herself sees his nakedness, it [is] a disgrace, and they shall be cut off {before} the eyes of {their people}; he has exposed his sister's nakedness--he must bear his guilt.

And you shall not expose the nakedness of your mother's sister, and you shall not expose your father's sister, because such a person has dishonored his close relative--they must bear their guilt.

and for his sister, a virgin, [who is] closest to him, {who has not had a husband}--for her he may defile himself.
