'Roofs' in the Bible

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

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