Then will I make their waters deep, and cause their rivers to run like oil, saith the Lord GOD.
Then will I make their waters deep - rather, 'then will I make their waters to subside' х 'ashqiya`
(H8257)] - literally, 'to sink in the deep' (Fairbairn).
And cause their rivers to run like oil - emblem of quietness. No longer shall they descend violently as the overflowing Nile on other countries, but shall be still and sluggish in political action.
