'Mountains' in the Bible

They sacrifice on the tops of the mountains, and burn incense on the hills, under oaks and poplars and terebinths, because its shade is good. Therefore your daughters play the prostitute, and your brides commit adultery.

The high places also of Aven, the sin of Israel, will be destroyed. The thorn and the thistle will come up on their altars. They will tell the mountains, "Cover us!" and the hills, "Fall on us!"
