The hills did tremble; a metaphorical and hyperbolical description of a grievous calamity, familiar in the prophets, as Isa_64:1,2 Jer 4:24, and in other authors.
His hand is stretched out still, ready to give you another and a sorer blow. This is not the end, as you vainly imagine, but, if you repent not, the beginning, of your sorrows, and an earnest of further calamities.
