'Heights' in the Bible

That one will live [on the] heights; [the] fortresses of rocks [will be] his refuge. His food [will] be given; his waters [will] endure.

I will open rivers on [the] barren heights and fountains in [the] midst of [the] valleys. I will make [the] wilderness like a pool of water and [the] land of dryness like springs of water.

saying to the {prisoners}, "Come out!" to those who [are] in darkness, "Show yourselves!" they shall feed {along} [the] ways, and their pasturage [shall be] on all [the] barren heights.

then you shall take your pleasure in Yahweh, and I will make you ride upon [the] heights of [the] earth, and I will feed you the heritage of Jacob your ancestor, for the mouth of Yahweh has spoken."
