John Gill Commentary Job 38:14

"It is changed as clay under the seal; And [all things] stand forth as a garment:" — Job 38:14 (ASV)

It is turned as clay [to] the seal
As the clay receives a different form by the impress of the seal upon it, so the earth appears in a different manner by the spring of morning light upon it; in the darkness of the night nothing of its form and beauty is to be seen; it is a mere "tohu" and "bohu", like the chaos, (Genesis 1:2) ; its rising hills, and spreading dales, and beautiful landscapes, cannot be observed with pleasure; but when the light breaks forth in the morning, it is seen in all its beauty and glory: of the change the light of the Gospel makes in men, see (2 Corinthians 3:18) ;

and they stand as a garment ;
or things stand upon it as a garment, as Mr. Broughton renders the words; herbs, plants, and trees, unseen in the night, stand up like a vesture to the earth in the morning light; and as they are clothed themselves, they are a garment to that, which now puts on another and beautiful habit; the pastures are clothed with flocks, and the valleys covered with corn, and the whole earth with light itself, as with a garment: and as beautifully do men made light in the Lord appear; see (Isaiah 41:10) (Revelation 3:4Revelation 3:5) (12:1) .
