Adam Clarke Bible Commentary

By what way is the light parted - Who can accurately describe the cause and operation of a thunder cloud, the cause, nature, and mode of operation of the lightning itself? Is it a simple element or compound substance? What is its velocity? and why not conductible by every kind of substance, as it is known to exist in all, and, indeed, to be diffused through every portion of nature? How is it parted? How does it take its zigzag form? this is the curious, indescribable, and unknown parting. Are all the causes of positive and negative electricity found out? What are its particles, and how do they cohere, and in what order are they propagated? Much has been said on all these points, and how little of that much satisfactorily! Scattereth the east wind upon the earth? - קדים kadim, the eastern storm, euroclydon, or levanter.
