'High Places' in the Bible

For a fire has gone out of Heshbon, a flame from the city of Sihon. It has devoured Ar of Moab, the lords of the high places of the Arnon.

And it came to pass in the morning, that Balak took Balaam, and brought him up into the high places of Baal, and he saw from there the outmost part of the people.

then ye shall drive out all the inhabitants of the land from before you, and destroy all their figured [stones], and destroy all their molten images, and demolish all their high places.
