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 (a) 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, Exo 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 Psa 18:14, so Aben Ezra; but Kimchi interprets them of hailstones.
