'High Place' 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.

It happened in the morning, that Balak took Balaam, and brought him up into the high places of Baal; and he saw from there the utmost part of the people.

then you shall drive out all the inhabitants of the land from before you, destroy all their stone idols, destroy all their molten images, and demolish all their high places.
