'Roof' in the Bible

One evening David got up from his bed and strolled around on the roof of the palace. From the roof he saw a woman bathing—a very beautiful woman.

So they pitched a tent for Absalom on the roof, and he slept with his father’s concubines in the sight of all Israel.

David was sitting between the two gates when the watchman went up to the roof of the gate and over to the wall. The watchman looked out and saw a man running alone.
