Baruch is named after Baruch ben Neriah, Jeremiah's scribe who is mentioned at Baruch 1:1 and has been presumed to be the author of the whole work. It is a reflection of a late Jewish writer on the circumstances of Jewish exiles from Babylon. The language of Baruch and Letter of Jeremiah might suggest that they should be classified as prophecy, but the frame is a literary device. The content sometimes speaks of prophecy, but at other times it relates more to wisdom, and this is how the two books are categorized. Since Baruch and Letter of Jeremiah circulated together in ancient Bibles, the Letter of Jeremiah was often numbered as Baruch 6.
