'Hills' in the Bible

They offer sacrifices on the mountain tops, burning offerings on the hills, under oaks, poplars, and terebinth trees, since their shade is very good. Therefore your daughters are prostitutes and your daughters-in-law commit adultery.

Destroyed will be the high places of Aven, that are the sin of Israel. Both thorn and thistle will grow up over their altars. They will call out to the mountains, "Cover us!' and to the hills, "Fall on us!'
