[Start reading: Isaiah 1](https://blessbible.app/bible/isaiah/1/) Chapters 1–66: [1](https://blessbible.app/bible/isaiah/1/) … [66](https://blessbible.app/bible/isaiah/66/) ## About Isaiah About Isaiah · Prophetic oracles Isaiah is the greatest of the prophetic books, spanning judgment and consolation: threats against a corrupt Jerusalem, comfort for exiles in Babylon, and visions of a restored people and a suffering servant who bears the sins of many. The prophet Isaiah ministered in the eighth century before Christ; the book that bears his name reflects his school and tradition carried through later crises, a formation history scholars continue to discuss. It was written to insist, across every disaster, that the Holy One of Israel governs history. The New Testament quotes it more than any prophet, and the Church has called it the fifth Gospel. *Isaiah in Bless* | | | |---|---| | Testament | Old Testament — book 27 of 46, 27 of 73 in the Bible | | Canon | Protocanonical (in every Christian canon) | | Chapters | 66 | | Verses | 1,292, as Bless numbers them | | In the Douay-Rheims | Isaias | | Latin | Clementine Vulgate, 65 of 66 chapters | | Bp.
