Charles H. Spurgeon on Psalms 77:17

The clouds poured out water. Obedient to the Lord, the lower region of the atmosphere yielded its aid to overthrow the Egyptian host. The cloudy chariots of heaven hurried forward to discharge their floods. The skies sent out a sound. From the loftier aerial regions thundered the dread artillery of the Lord of Hosts. Peal on peal the skies sounded over the heads of the routed enemies, confusing their minds and adding to their horror. Thine arrows also went abroad. Lightnings flew like bolts from the bow of God. Swiftly, hither and thither, went the red tongues of flame, on helm and shield they gleamed; anon with blue bale fires revealing the innermost caverns of the hungry sea which waited to swallow up the pride of Mizraim. Behold, how all the creatures wait upon their God, and show themselves strong to overthrow his enemies.
