Jeremiah
Conflict with false prophets
While Jeremiah was prophesying the coming destruction, he denounced a number of other prophets who were prophesying peace.
Historicity
The consensus is that there was a historical prophet named Jeremiah and that portions of the book probably were written by Jeremiah or his scribe Baruch. Views range from the belief that the narratives and poetic sections in Jeremiah are contemporary with his life (W. L. Holladay), to the view that the work of the original prophet is beyond identification or recovery (R. P. Carroll).
Jeremiah
Jeremiah (c. 650 – c. 570 BC), also called Jeremias, and occasionally in older English texts Jeremy, was one of the major prophets of the Hebrew Bible. According to Jewish tradition, Jeremiah authored the book that bears his name, the Books of Kings, and the Book of Lamentations, with the assistance and under the editorship of Baruch ben Neriah, his scribe and disciple.
