Now also many nations are gathered against thee, that say, Let her be defiled, and let our eye look upon Zion.
Now also many nations are gathered against thee - the subject peoples composing Babylon's armies: and also Edom, Ammon, Moab, etc, who exulted in Judah's fall (Lamentations 2:16; Obadiah 1:11-13).
That say, Let her be defiled - metaphor from a virgin. Let her be defiled (i:e., outraged by violence and bloodshed).
And let our eye look upon Zion - and let our eye gaze insultingly on her shame and sorrow (Micah 7:10). Her foes desired to feast their eyes on her calamities.
