Leviticus 18:15-17

New American Standard Bible

^15 (A)You shall not uncover the nakedness of your daughter-in-law. She is your son’s wife; you shall not uncover her nakedness. ^16 (B)You shall not uncover the nakedness of your brother’s wife; it is your brother’s nakedness. ^17 (C)You shall not uncover the nakedness of a woman and of her daughter, nor shall you take her son’s daughter or her daughter’s daughter, to uncover her nakedness; they are blood relatives. It is an outrageous sin.
