Occasionally referred to as 1 Baruch, the book is named after Baruch ben Neriah, Jeremiah’s scribe, its purported author. It contains reflections on the theology and history of Israel, discussions of wisdom, and addresses to residents of Jerusalem and the Diaspora. Some scholars propose that it was written during or shortly after the period of the Maccabees.
Although the earliest known manuscripts of Baruch are in Greek, there is linguistic evidence that the beginning of Baruch (1:1-3:8) was originally translated from a Semitic language.
