'Roof' in the Bible

One evening David got up from his bed and walked around on the roof of his palace. From the roof he saw a woman bathing. Now this woman was very attractive.

So they pitched a tent for Absalom on the roof, and Absalom had sex with his father's concubines in the sight of all Israel.

Now David was sitting between the inner and outer gates, and the watchman went up to the roof over the gate at the wall. When he looked, he saw a man running by himself.
