<P> Modern scholars divide the Book of Isaiah into three parts, each with a different origin: "First Isaiah", chapters 1--39, containing the words of the historical 8th century BCE prophet Isaiah and later expansions by his disciples; "Deutero - Isaiah" (chapters 40--55), by an anonymous Jewish author in Babylon near the end of the Babylonian captivity; and "Trito - Isaiah" (chapters 56--66), by anonymous disciples of Deutero - Isaiah in Jerusalem immediately after the return from Babylon (although some scholars suggest that chapters 55--66 were written by Deutero - Isaiah after the fall of Babylon .) This orderly sequence of pre-exilic, exilic and post-exilic material is somewhat misleading, as significant editing has clearly taken place in all three parts . </P> <P> Jeremiah lived in the late 7th and early 6th centuries BCE . The Book of Jeremiah presents Baruch ben Neriah as the prophet's companion who writes his words on several occasions, and there has accordingly been much speculation that Baruch could have composed an early edition of the book . In the early 20th century Sigmund Mowinckel identified three types of material in the book, Jeremiah 1--25 (Type A) being the words of Jeremiah himself, the biographic prose material (Type B) by an admirer writing c. 580--480 BCE, and the remainder (Type C) from later periods . There has been considerable debate over Mowinckel's ideas, notably the extent of the Jeremiah material and the role of Baruch, who may have been the author of the Type B material . It is generally agreed that the book has strong connections with the Deuteronomistic layers from the Former Prophets, recapitulating in modern terms the traditional idea that Jeremiah wrote both his own book and the Books of Kings . </P> <P> The Book of Ezekiel describes itself as the words of Ezekiel ben - Buzi, a priest living in exile in the city of Babylon between 593 and 571 BCE . The various manuscripts, however, differ markedly from each other, and it is clear that the book has been subjected to extensive editing . While Ezekiel himself may have been responsible for some of this revision, there is general agreement that the book as we have it today is the product of a highly educated priestly circle that owed allegiance to the historical Ezekiel and was closely associated with the Temple . </P> <P> The Minor Prophets are one book in the Hebrew Bible, and many (though not all) modern scholars agree that the Book of the Twelve underwent a process of editing which resulted in a coherent collection . This process is believed to have reached its final form in the Persian period (538--332 BCE), although there is disagreement over whether this was early or late . For the individual books, scholars usually assume that there exists an original core of prophetic tradition which can be attributed to the figure after whom the book is named . The noteworthy exception is the Book of Jonah, an anonymous work containing no prophetic oracles, probably composed in the Hellenistic period (332--167 BCE). </P>
