'Barren Heights' in the Bible

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.
