The king and kingdom of Israel seemed to be something of the past. They were in exile, and every king they ever had failed them - even the best of them had passed away. God continued to speak through prophets to let His people know He was still pursuing them. Through the prophet Isaiah, the Lord told them that one day the promised Rescuer would come and take away their sorrow and suffering - and that he would take it upon himself. We can have joy because this Suffering Servant has taken our sorrow.
