'Mountaintops' in the Bible

Let the desert and its cities shout out, the towns where the nomads of Kedar live! Let the residents of Sela shout joyfully; let them shout loudly from the mountaintops.

Then you will know that I am the Lord -- when their dead lie among their idols around their altars, on every high hill and all the mountaintops, under every green tree and every leafy oak, the places where they have offered fragrant incense to all their idols.

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!

They sound like chariots rumbling over mountain tops, like the crackling of blazing fire consuming stubble, like the noise of a mighty army being drawn up for battle.

Look, the Lord is coming out of his dwelling place! He will descend and march on the earth's mountaintops!
