Albert Barnes Commentary Psalms 107:35

"He turneth a wilderness into a pool of water, And a dry land into watersprings." — Psalms 107:35 (ASV)

He turneth the wilderness into a standing water - A pool; a lake. See the notes at Isaiah 35:6-7.

And dry ground into water-springs - Not merely watering it with rain from heaven, but causing gushing fountains to break forth, and to flow continually, diffusing fertility and beauty everywhere.
