[1] Of all the prophets, Jeremiah comes through most clearly as a person, ruminating to his scribe Baruch about his role as a servant of God with little good news for his audience.
[4] Authentic oracles of Jeremiah are probably to be found in the poetic sections of chapters 1 through 25, but the book as a whole has been heavily edited and added to by the prophet's followers (including, perhaps, his companion, the scribe Baruch) and later generations of Deuteronomists.
The non-biographical prose passages, such as the Temple sermon in chapter 7 and the covenant passage in 11:1–17, are scattered throughout the book; they show clear affinities with the Deuteronomists, the school of writers and editors who shaped the series of history books from Judges to Kings, and while it is unlikely they come directly from Jeremiah,[citation needed] they may well have their roots in traditions about what he said and did.
These passages, dealing with Israel's unfaithfulness to God, the call to repentance, and attacks on the religious and political establishment, are mostly undated and have no clear context, but it is widely accepted that they represent the teachings of Jeremiah and are the earliest stage of the book.
In these poems the prophet agonises over the apparent failure of his mission, is consumed by bitterness at those who oppose or ignore him, and accuses God of betraying him.
[11] Jeremiah exists in two versions: a Greek translation, called the Septuagint, dating from the last few centuries BCE and found in the earliest Christian manuscripts, and the Masoretic Hebrew text of traditional Jewish bibles.
Equivalents of both versions were found among the Dead Sea Scrolls, so it is clear that the differences mark important stages in the transmission of the text.

The Greek stage, looking forward to the fall of Babylon and aligning in places with Second Isaiah, had already seen major redaction (editing) in terms of overall structure, the superscriptions (sentences identifying following passages as the words of God or of Jeremiah), the assignment of historical settings, and arrangement of material, and may have been completed by the late Exilic period (last half of the 6th century BCE); the initial stages of the Masoretic Hebrew version may have been written not long afterwards, although chapter 33:14–26[17] points to a setting in post-exilic times.
[18] According to its opening verses the book records the prophetic utterances of the priest Jeremiah son of Hilkiah, "to whom the word of YHWH came in the days of king Josiah" and after.
Jeremiah lived during a turbulent period, the final years of the kingdom of Judah, from the death of king Josiah (609 BCE) and the loss of independence that followed, through the destruction of Jerusalem by the Babylonians and the exile of much its population (587/586).
[25][26] In these five passages, Jeremiah expresses his discontent with the message he is to deliver, but also his steadfast commitment to the divine call despite the fact that he had not sought it out.
The understanding of the early Christians that Jesus represented a "new covenant"[42] is based on Jeremiah 31:31–34, in which a future Israel will repent and give God the obedience he demands.
