The nations shall rush like the rushing of many waters: but God shall rebuke them, and they shall flee far off, and shall be chased as the chaff of the mountains before the wind, and like a rolling thing before the whirlwind.
(God) shall rebuke them, and they shall flee far off - rather, 'God rebuketh (Psalms 9:5) them, and they flee-are chased;' the event is set before the eyes as actually present, not future.
Chased as the chaff of the mountains. Threshing-floors in the East are in the open air, on elevated places, so as to catch the wind which separates the chaff from the wheat (Psalms 83:13; Hosea 13:3).
Like a rolling thing - anything that rolls; stubble.
