'Hills' in the Bible

They sacrifice upon the tops of the mountains, and burn incense upon the hills, under oaks and poplars and elms, because the shadow thereof is good: therefore your daughters shall commit whoredom, and your spouses shall commit adultery.

Blow the horn in Gibeah,The trumpet in Ramah [the lofty hills on Benjamin’s northern border].Sound the alarm at Beth-aven:“Behind you and coming after you [is the enemy], O Benjamin [be on guard]!”

The high places also of Aven, the sin of Israel, shall be destroyed: the thorn and the thistle shall come up on their altars; and they shall say to the mountains, Cover us; and to the hills, Fall on us.
