understanding Isaiah, IMHO requires a bit of knowledge of standard symbolismAre you even reading Isaiah 49 or just copying something someone once told you?
Isaiah 49 speaks of 2 or possibly 3 subjects -- the first part is speaking of the nation of Israel, and/or possibly of the prophet, Isaiah, who is referred to as the nation he represents. And the second section, starting in verse 7, where it mentions "redeemer" speaks of God pretty explicitly.
You are very confused. Try reading the things you reference first so you won't look so ignorant.
