Yahweh, when you went forth out of Seir, When you marched out of the field of Edom, The earth trembled, the sky also dropped, Yes, the clouds dropped water.
and the heavens dropped, the clouds also dropped water; which, as it may literally refer to the storm and tempest of rain that might be then as now, see Judges 4:15, so may figuratively express the panic great personages, comparable to the heavens and the clouds in them were thrown into, when their hearts melted like water, or were like clouds dissolved into it.
