Charles Ellicott Commentary Psalms 46:6

"The nations raged, the kingdoms were moved: He uttered his voice, the earth melted." — Psalms 46:6 (ASV)

The absence of conjunctions, and the sudden change from the preterite to the future, lend a vividness to the picture.
Raged heathen, tottered kingdoms
Gave with His voice (the signal) (and lo!)

Melts the earth.
