Isaiah, whose name means ''salvation of the Lord'' or ''the Lord will save,'' is prominently placed at the beginning of the section. He is often called the prophet of redemption.
The prophecies of Isaiah were delivered during the reigns of four kings of Judah: Uzziah, Jotham, Ahaz, and Hezekiah (Isa 1:1). He spoke primarily to Judah prior to the exile. In the opening verse, he stated that he was about to relate a vision he saw concerning Judah and Jerusalem. He meant precisely that. It was not a vision about the church, but about Judah and Jerusalem. Great principles can be learned from God's dealings with men of old that apply to people of all ages. The mystery of Christ and His church, however, was not revealed to the Old Testament prophets.
One Bible scholar has suggested that chapters 1 through 39 breathe with the Old Testament spirit of judgment and warning, and chapters 40 - 66 breathe with the New Testament spirit of grace and peace.
