About half of Jeremiah is poetry and half prose. But poetry and prose appear side by side in many sections of the book; several literary units contain both forms of composition.
Scholars have identified three types of literature (genre) in Jeremiah: poetic sayings or oracles (so-called Type A material), prose narratives that are largely biographical and historical (so-called Type B material), and prose speeches or discourses (so-called Type C material).31
Several generations of scholars have held that the poetic oracles toward the first part of the book represent Jeremiah's original sayings, and the historical and biographical narratives that follow were the product of Baruch, Jeremiah's scribe. This view, while a common one, contains serious problems, and many competent authorities have pointed out the inconsistencies of this position. I mention it here because it is a common view, not because I accept it. I do not.
