This chapter continues describing the "suffering servant." He grows up in front of God like a plant. People ignore him because he doesn't look particularly majestic. They all reject him and despise him, and he spends his whole life suffering.
But he pays off everyone's sins with all this horrible suffering. No one realizes it, but it works. The people return to God like sheep to their shepherd.
Meanwhile, the servant goes like a sheep to the slaughter, bearing the people's punishment silently. He is taken away by a "perversion of justice," and is buried with the wicked and then with the rich.
God organized all of this to pay off the people's transgressions. So, in the end the servant will be alright. He'll see light through his troubles and find a place with the righteous and mighty as a reward for his atonement.
