Job 38:37,38 - Joseph Benson’s Commentary on the Old and New Testaments

Who can number the clouds in wisdom? Who can wisely search, and exactly find out, the number of the clouds? which are indeed numberless, and filled with water as the next clause implies. Or who can stay the bottles of heaven? Can prevent the rain from being poured upon the earth out of the clouds, in which it is kept as in bottles; when the dust groweth into hardness When the earth grows very hard, in the time of a great drought; and the clods cleave fast together Become close and compact. Or the condition of the earth may be intended presently after a fall of rain, when the ground, which in the time of drought was much of it dissolved into dust, is now, by the rain, cemented or united together.
