'Roofs' in the Bible

In their streets they are girded with sackcloth; on their roofs, and in their broadways, every one howleth, melted into tears.

And the houses of Jerusalem and the houses of the kings of Judah shall be as the place of Topheth, defiled, all the houses upon whose roofs they have burned incense unto all the host of the heavens, and have poured out drink-offerings unto other gods.

And the Chaldeans, that fight against this city, shall come in and set fire to this city, and shall burn it, and the houses upon whose roofs they have offered incense unto Baal, and poured out drink-offerings unto other gods, to provoke me to anger.
