Jeremiah 49:22

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; (See Gill on Jeremiah 48:41).
