Micah 1:4 - Ellicott's Commentary On The Whole Bible

The mountains shall be molten. — The manifestations of the presence of God are taken from the description of the giving of the Law, when “the hills melted like wax at the presence of the Lord, at the presence of the Lord of the whole earth” (Psalms 97:5). Dean Stanley refers the imagery to the memorable earthquake mentioned in Amos 1:1 : — “Mountains and valleys are cleft asunder, and melt as in a furnace; the earth heaving like the rising waters of the Nile; the sea bursting over the land; the ground shaking and sliding as, with a succession of shocks, its solid framework reels to and fro like a drunkard” (Jewish Church, Lect. 37).
