1. Isaiah - The evangelical prophet
   - Vision of God's holiness in the temple
   - Extensive messianic prophecies (virgin birth, suffering servant)
   - Most quoted OT prophet in the New Testament

2. Ezra - Priest and scribe
   - Led second wave of exiles from Babylon
   - Reestablished centrality of God's Law
   - Religious reform and covenant renewal

3. Nehemiah - Rebuilding leader
   - Rebuilt Jerusalem's walls in 52 days
