He withholdeth the waters - From the clouds and springs. He has control over the rains and the fountains; and when these are withheld, rivers and lakes become dry. The Syriac renders this, - “if he rebuke the waters,” supposing that there might perhaps be an allusion to the drying up of the Red Sea, or the formation of a passage for the Israelites. But it is remarkable that in the argument here there is no allusion to any historical fact, not to the flood, or to the destruction of Sodom and Gomorrah, or to the passage through the Red Sea, though these occurrences would have furnished so appropriate illustrations of the points under discussion. Is it to be inferred that Job had never heard of any of those events? Or may it have been that the lessons which they were adapted to teach had been actually embodied in the proverbs which he was using, and furnished well-known illustrations or the basis of such apothegms?
He sendeth them out, and they overturn the earth - Such inundations may have occurred in the swollen torrents of Arabia, and indeed are so common everywhere as to furnish a striking illustration of the power and sovereign agency of God.
