“There were thunders and lightning.” The symbol of sudden and terrific dispersion and destruction of the forces of war. As the coruscation of lightning and thunder shake the natural heavens, or air, so symbolic thunders shake the political and existing government of men. Isa. 29:6, Job 39:25, 1 Sam. 2:10, Psa. 18:7.
