Surely I will fill thee, etc. This is the rendering of Hitzig and Graf; the enemies are compared to locusts, as in Jeremiah 46:23. But the expression, "to fill a city with men," is more naturally taken of the increase of the population of the city; and it is better to render, with Ewald and Keil, "Even though [or, 'Surely even though'] I have filled thee with men, as with locusts, they shall raise over thee the cheer of the vintage;" i.
e. the millions of Babylon's population will not save her from the most utter ruin. For the vintage cheer, see on Jeremiah 25:30; and for the figures, see especially, Isaiah 63:1-6.
