Charles Spurgeon Commentary Isaiah 35:7

"And the glowing sand shall become a pool, and the thirsty ground springs of water: in the habitation of jackals, where they lay, shall be grass with reeds and rushes." — Isaiah 35:7 (ASV)

The greenest spots your eye ever rested upon are just there where the grass is so rooted in the morass that it is always green with a delicate tinge, and the reeds and rushes spring up abundantly.

O God, make poor parched hearts become like this! You barren ones, you desolate ones, he can give you the best verdure that is possible. Your hearts shall be as green and fresh as the spots where there is grass with reeds and rushes.
