Verse 15. So tremendous was the shock of God's assault in arms that the order of nature was changed, and the bottoms of rivers and seas were laid bare.
The channels of waters was seen; and the deep cavernous bowels of the earth were upheaved till the foundations of the world were discovered. What will not Jehovah's rebuke do? If the blast of the breath of thy nostrils, O Lord, be so terrible, what must thine arm be? Vain are the attempts of men to conceal anything from him whose word unbars the deep, and lifts the doors of earth from their hinges! Vain are all hopes of resistance, for a whisper of his voice makes the whole earth quail in abject terror.
