Jeremiah

Jeremiah (Born::642 BC-Died::587 BC) ("Name means::YHWH exalts") was a prophet during the fall of Jerusalem. He is sometimes referred to as "the weeping prophet" because of his empathetic writings for the suffering of his people (both in the present, before his eyes, and in the future, through prophecy). He was, by far, the most prolific of the Old Testament prophets.

Book of Jeremiah
The Book of Jeremiah is an eponymous collection of prophecies written by the Prophet Jeremiah, during the fall of Jerusalem and the capture and exile of the Israelites by Babylon. These prophecies make it clear that although the suffering the people experience is at the hand of King Nebuchadnezzar, he is only acting (unwittingly) in accordance with God's will as a consequence for Israel's unrepentant sin. Jeremiah also prophesies very specifically about the length of the captivity, and the return of the exiles.

Virtually all modern scholars agree that most of the Book of Jeremiah is the work of a single author, and there is no credible evidence to doubt the authorship of Jeremiah himself. However, the text of the book makes it clear that chapter 52 was appended by another writer (most likely Baruch, Jeremiah's secretary). This final chapter is historical, not prophetic, in nature, and mostly parallels information given in 2 Kings.

The Book of Jeremiah is not only the longest book of prophecy in the Bible, in the original Hebrew, it is the longest single book (by total number of words) in the Bible.
