The Book of Isaiah is the first of the earlier Prophets in the Hebrew Bible and the first of the Major Prophets in the Christian Old Testament. Isaiah is a book that unveils the full dimensions of God's judgment and salvation. God is "the Holy One of Israel" (see 1:4; 6:1 and notes) who must punish his rebellious people (1:2) but will afterward redeem them (41:14,16).
