God's 'cannot' answers Lot's 'cannot.' His power is limited by His own solemn purpose to save His faltering servant. The latter had feared that, before he could reach the mountain, 'the evil' would overtake him. God shows him that his safety was a condition precedent to its outburst. Lot barred the way. God could not 'let slip the dogs of' judgment, but held them in the leash until Lot was in Zoar. Very awful is the command to make haste, based on this impossibility, as if God were weary of delay, and more than ready to smite. However we may find anthropomorphism in these early narratives, let us not forget that, when the world has long been groaning under some giant evil, and the bitter seed is grown up into a waving forest of poison, there is something in the passionless righteousness of God which brooks no longer delay, but seeks to make 'a short work' on the earth.
3. So we are brought face to face with the grim story of the destruction. There is a world of tragic meaning in the simple note of time given. 'The sun was risen upon the earth when Lot entered into Zoar.' The low-lying cities of the plain would lie in shadow for some time before the sun topped the eastern hills. What a dawn! At that joyous hour, just when the sunshine struck down on the smiling plain, and lake and river gleamed like silver, and all things woke to new hopes and fresh life, then the sky darkened, and the earth sank, and horrible rain of fiery bitumen fell from the black pall, salt mud poured in streams, and over all hung a column of fat, oily smoke. It is not my province to discuss the physical cause of the destruction; but I may refer to the suggestions of Sir J. W. Dawson, in his _Egypt and Syria_, and in _The Expositor_ for May 1886, in which he shows that great beds of bituminous limestone extend below the Jordan valley and much of the Dead Sea, and that the escape of inflammable gag from these through the opening of a fissure along a great 'line of fault,' is capable of producing all the effects described. The 'brimstone' of the Authorised Version is probably rather some form of bituminous matter which would be carried into the air by such an escape of gas, and a thick saline mud would accompany the eruption, encrusting anything it reached. Subsidence would follow the ejection of quantities of such matter; and hence the word 'overthrew,' which seems inappropriate to a mere conflagration, would be explained.
