Isaiah 35:7

“And the parched ground shall become a pool, and the thirsty land springs of water, &c.] Such persons who have been like the parched earth, barren and unfruitful, or like the earth scorched with the sun, filled with a sense of divine wrath, and thirsting, like the dry earth, after the grace of God, Christ, and his righteousness, shall be comforted and refreshed, and filled with the grace of God: or such who have been scorched and parched with the heat of persecution, from the antichristian party, and have been thirsting after deliverance from it, shall now enjoy peace and prosperity: in the habitation of dragons, where each lay; in kingdoms, cities, and towns, inhabited by men, comparable to…”

“parched ground--rather, "the mirage (Hebrew, Sharab, 'the sun's heat') shall become a (real) lake."

Rushes - Those dry and parched deserts, in which dragons have their abode, shall yield abundance of grass, and reeds, and rushes, which grow only in moist ground. Isaiah 35:8”

“the parched: Isa 29:17, Isa 44:3, Isa 44:4; Mat 21:43; Luk 13:29; Joh 4:14, Joh 7:38; Co1 6:9-11 in the: Isa 34:13; Hos 1:10, Hos 1:11; Act 26:18; Jo1 5:19, Jo1 5:20; Rev 12:9-12, Rev 18:2, Rev 20:2, Rev 20:3 grass with reeds: or, a court for reeds, etc. Isa 19:6 Isaiah 35:8”
