Charles Ellicott Commentary Isaiah 46:11

"calling a ravenous bird from the east, the man of my counsel from a far country; yea, I have spoken, I will also bring it to pass; I have purposed, I will also do it." — Isaiah 46:11 (ASV)

Calling a ravenous bird. —Cyrus is thus described as Nebuchadnezzar is in Jeremiah 49:22; Ezekiel 17:3. The image derives a special significance from the fact that the standard carried by Cyrus and his successors was a golden eagle (Xenophon, Cyropaedia 7.1.4; Anabasis 1.10.12). (Luke 17:37.) The “sun-rising” is, of course, Persia; the “far country” probably represents Media.

I have spoken. —The word of Jehovah, unlike that of the false gods, passes into a sure and immediate act.
