2 Baruch is a Jewish apocryphal text thought to have been written in the late 1st century CE or early 2nd century CE, after the destruction of the Temple in CE 70. It is attributed to the biblical figure Baruch ben Neriah (c. 6th century BC) and so is associated with the Old Testament, but not regarded as scripture by Jews or by most Christian groups. It is included in some editions of the Peshitta, and is part of the Bible in the Syriac Orthodox tradition. It has 87 sections (chapters).
2 Baruch is also known as the Apocalypse of Baruch or the Syriac Apocalypse of Baruch (used to distinguish it from the Greek Apocalypse of Baruch). The Apocalypse proper occupies the first 77 chapters of the book. Chapters 78–87 are usually referred to as the Letter of Baruch to the Nine and a Half Tribes.
