Behold, he shall come up, and fly as the eagle,.... The Targum is,
"behold, as an eagle comes up and flies, so shall a king come up with his army;''
the king of Babylon with his army, compared to an eagle for his swiftness and voraciousness, as before to a lion for his strength and fierceness:
and spread his wings over Bozrah; besiege that city, invest it, and seize upon it; very fitly are the wings of an army expressed by the wings of this bird, denoting both their extent and force; the same is said concerning Moab, Jeremiah 48:40;
and at that day shall the heart of the mighty men of Moab be as the heart of a woman in her pangs; when just ready to be delivered; not only weak and timorous, but full of anguish, and: quite dispirited;
