'Dryness' 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.

And they did not say, 'Where [is] Yahweh, the one who brought us up from the land of Egypt, the one who led us in the desert, in a land of desert plains and gorges, in a land of dryness and deep darkness, in a land {that no one passes through}, and no human lives there?'
