The clouds poured out water: the skies sent out a sound: thine arrows also went abroad. The clouds poured out water - It appears from this that there was a violent tempest at the time of the passage of the Red Sea. There was a violent storm of thunder, lightning, and rain. These three things are distinctly marked here.
1. "The skies sent out a sound:" the Thunder.
2. "Thine arrows went abroad:" the Lightning.
3. "The clouds poured out water:" the Rain. In the next verse we have,
4. An Earthquake: "The earth trembled and shook," Psalms 77:18.
