The clouds poured out water
This, with some other circumstances which follow, are not related by Moses in the history of this affair; but as they are here recorded by an inspired penman, there is no doubt to be made of the truth of them; besides Josephus F1 relates the same things; he says, that at the time when the Egyptians were drowned in the Red sea, rains descended from heaven, and there were terrible thunders, lightnings, and thunderbolts; this was when the Lord looked through the cloud, and troubled the host of the Egyptians, ( Exodus 14:24 ) ,
the skies sent out a sound;
or the airy clouds, the lighter ones, and which were higher in the heavens, as the others before mentioned were thick clouds, full of water, and hung lower; these were thunderclouds, and thunder is the sound which they sent forth, as in the following verse:
thine arrows also went abroad:
that is, lightnings, as in ( Psalms 18:14 ) , so Aben Ezra; but Kimchi interprets them of hailstones.
