'Hill' in the Bible
And you will be certain that I am the Lord, when their dead men are stretched among their images round about their altars on every high hill, on all the tops of the mountains, and under every branching tree, and under every thick oak-tree, the places where they made sweet smells to all their images.
For when I had taken them into the land which I made an oath to give to them, then they saw every high hill and every branching tree and made their offerings there, moving me to wrath by their offerings; and there the sweet smell of their offerings went up and their drink offerings were drained out.
And my sheep went out of the way, wandering through all the mountains and on every high hill: my sheep went here and there over all the face of the earth; and no one was troubled about them or went in search of them.
