Isaiah 11

This must have been a confusing sermon for the people of Judah. First Isaiah spoke about God's coming judgment, now he speaks of a kingdom of harmonious peace. How could Isaiah be speaking of a new king when a son of David was already sitting on the throne? Why would God refer to a road out of Assyria when none of God's people were in captivity? How would these words have been received?  No matter how hard you listen you won't understand (6:9). That was God's earlier message to Judah.
