The clouds poured out water - Margin, “The clouds were poured forth with water.” The translation in the text is the more correct. This is a description of a storm; but to what particular storm in history does not appear. It was evidently some exhibition of the divine greatness and power in delivering the children of Israel, and may have referred to the extraordinary manifestation of God at Mount Sinai, amidst lightnings, and thunders, and tempests. Exodus 19:16. For a general description of a storm, as illustrating this passage, see Job 36:26-33, notes; Job 37:1-5, notes; and Psalms 29:1-11.
The skies sent out a sound - The voice of thunder, which seems to come from the sky.
Thine arrows also - The lightnings - compared with burning or ignited arrows. Such arrows were anciently used in war. They were bound round with rags, and dipped in some combustible substance - as turpentine - and shot into houses, grain-fields, haystacks, or towns, for the purpose of setting them on fire. It was not unnatural to compare the rapid lightnings with such blazing arrows.
Went abroad - They moved rapidly in all directions.
