John Gill Commentary Job 38:27

"To satisfy the waste and desolate [ground], And to cause the tender grass to spring forth?" — Job 38:27 (ASV)

To satisfy the desolate and waste [ground]
Which is exceeding desolate, and therefore two such words are used to express it; which is so dry and thirsty that it is one of the four things that say not it is enough, (Proverbs 30:16) ; and yet God can and does give it rain to its full satisfaction, (Psalms 104:13) ; so the Lord satisfies souls, comparable to dry and thirsty ground, by his word and ordinances, with the goodness and fatness of his house; see (Psalms 63:1–5) (65:4) ;

and to cause the bud of the tender herb to spring forth ?
grass for the cattle, and herb for the service of men, (Psalms 104:14) ; of like use is the word in a spiritual sense for the budding and increase of the graces of the Spirit in the Lord's people; see (Deuteronomy 32:2) (Isaiah 55:10Isaiah 55:11) .
