Micah 1:4

New English Translation

⁴The mountains will crumble^[a] beneath him,
and the valleys will split apart^[b]
like wax before a fire,
like water dumped down a steep slope.

Micah 1:4 tn Or “melt” (NAB, NASB, NIV, NRSV, NLT). This is a figurative description of earthquakes, landslides, and collapse of the mountains, rather than some sort of volcanic activity (note the remainder of the verse).
Micah 1:4 tn Or “rupture.” This may refer to the appearance of a valley after the blockage of a landslide has effectively divided it.
