'Roof' in the Bible

And it came to pass at eventide, that David arose from off his bed, and walked upon the roof of the king's house: and from the roof he saw a woman bathing; and the woman was very beautiful to look upon.

Now David was sitting between the two gates: and the watchman went up to the roof of the gate unto the wall, and lifted up his eyes, and looked, and, behold, a man running alone.
