'Hills' in the Bible

They sacrifice on the mountaintops, and burn offerings on the hills; they sacrifice under oak, poplar, and terebinth, because their shade is so pleasant. As a result, your daughters have become cult prostitutes, and your daughters-in-law commit adultery!

The high places of the "House of Wickedness" will be destroyed; it is the place where Israel sins. Thorns and thistles will grow up over its altars. Then they will say to the mountains, "Cover us!" and to the hills, "Fall on us!"
