John Trapp on Micah 1:4

Verſe 4. And the mountaines ſhall be molten under him] This is to the ſelf-ſame ſenſe: Though men ſwell in their own eyes, to the hugeneſſe of ſo many mountains: and though gotten upon their hill of ice, they think they ſhall never be moved, Pſal. 30.6, 7. yet when God with his devouring fire, and everlaſting burnings comes in preſence, theſe craggie mountains ſhall ſoon diſſolve and melt as wax, they ſhall be as waters, poured down a deſcent, they ſhall flow as a land-flood, &c. By which ſimilitudes, and familiar compariſons is notably ſet forth the irreſiſtible wrath of God for the affrighting of hard-hearted ſinners, that they may take hold of his ſtrength, and make peace with him, Eſay 27.5.

The valleys alſo ſhall be cleft.] The poorer ſort alſo ſhall have their ſhare in the common calamity. God will neither ſpare the high for their might, nor the baſe for their meanneſſe, but Lords and loſels together, ſhall be as wax before the fire, &c.] Wax is a poor fence againſt fire, ſticks and ſtubble againſt a ſtrong torrent: ſo humane force, againſt divine judgements.
