'Heights' in the Bible

and he sacrificeth and maketh perfume in high places, and on the heights, and under every green tree.

You have mocked the Lord through your messengers.You have said:With my many chariotsI have gone up to the heights of the mountains,to the far recesses of Lebanon.I cut down its tallest cedars,its choice cypress trees.I came to its farthest outpost,its densest forest.
