Job 37:10

“By the breath of God frost is given, etc.] By the word of God, as the Targum; at his command it is, at his word it comes, and at his word it goes, (<19E715>Psalm 147:15-18); or by his will, as Ben Gersom interprets it, when it is his pleasure it should be, it appears; it may be understood of a freezing wind from the Lord, for a wind is sometimes expressed by the breath of his nostrils, (<191815>Psalm 18:15); and as the word “God” added to things increases the signification of them, as mountains of God are strong mountains; so the breath of God may signify a strong wind, as Sephorno notes, the north wind f1286; and the breadth of the waters is straitened; by the frost they are reduced and…”

“the breath of God--poetically, for the ice-producing north wind. frost--rather, "ice." straitened--physically accurate; frost compresses or contracts the expanded liquid into a congealed mass (Job 38:29-30; Psa 147:17-18).”

“By the breath of God frost is given - Not by the violent north wind, or by the whirlwind of the south, but God seems to “breathe” in a gentle manner, and the earth is covered with hoary frost. It appears in a still night, when there is no storm or tempest, and descends upon the earth as silently as if it were produced by mere breathing. Frost is congealed or frozen dew. On the formation and cause of dew, see the notes at Job 38:28. The figure is poetical and beautiful. The slight motion of the air, even when the frost appears, seems to be caused by the breathing of God. And the breadth of the waters is straitened - That is, is contracted by the cold; or is frozen over. The waters are…”

“The waters - The waters which had freely spread themselves before, are congealed and bound up in crystal fetters. Job 37:11”
