Leviticus 18:9; Leviticus 20:17; Ezekiel 22:11

xYou shall not uncover the nakedness of your sister, your father's daughter or your mother's daughter, whether brought up in the family or in another home.


17 iIf a man takes his sister, a daughter of his father or a daughter of his mother, and sees her nakedness, and she sees his nakedness, it is a disgrace, and they shall be cut off in the sight of the children of their people. He has uncovered his sister's nakedness, and he shall bear his iniquity.


11 pOne commits abomination with his neighbor's wife; qanother lewdly defiles his daughter-in-law; ranother in you violates his sister, his father's daughter.
