The Israelite who constructed a new home was required to build a parapet around the flat roof, which was often used to entertain guests.
فَهُنَاكَ يُوصَى ٱلْإِسْرَائِيلِيُّ ٱلَّذِي بَنَى بَيْتًا جَدِيدًا أَنْ يَصْنَعَ حَائِطًا لِلسَّطْحِ ،‏ إِذْ غَالِبًا مَا كَانَ يُسْتَعْمَلُ لِٱسْتِضَافَةِ ٱلنَّاسِ .‏
