Albert Barnes Commentary Ezekiel 17:3

"and say, Thus saith the Lord Jehovah: A great eagle with great wings and long pinions, full of feathers, which had divers colors, came unto Lebanon, and took the top of the cedar:" — Ezekiel 17:3 (ASV)

A great eagle ... - Probably the golden eagle, whose plumage has the variety of color here depicted. The eagle (the king of birds) is a natural representative of monarchs , and was an Assyrian emblem.

With great wings, longwinged - literally, “great of wing, long of pinion,” because he has swept victoriously over widely distant lands—of diverse colors, because his subjects are of various races and tongues.

Jerusalem is here called “Lebanon” because Lebanon is the proper home of the cedar.

The “highest branch” or “topshoot” is Jeconiah, the rightful king of Jerusalem; the “young twigs” are his children and the princes carried by Nebuchadnezzar to Babylon.
