اَللَّاوِيِّينَ 18:17

عَوْرَةَ ٱمْرَأَةٍ وَبِنْتِهَا لَا تَكْشِفْ. وَلَا تَأْخُذِ ٱبْنَةَ ٱبْنِهَا، أَوِ ٱبْنَةَ بِنْتِهَا لِتَكْشِفَ عَوْرَتَهَا. إِنَّهُمَا قَرِيبَتَاهَا. إِنَّهُ رَذِيلَةٌ.

Thou shalt not uncover the nakedness of a woman and her daughter, neither shalt thou take her son’s daughter, or her daughter’s daughter, to uncover her nakedness; for they are her near kinswomen: it is wickedness.
