The Book of Jubilees, sometimes called Lesser Genesis (Leptogenesis), is an ancient Jewish religious work of 50 chapters, considered canonical by the Ethiopian Orthodox Church as well as Bete Israel (Ethiopian Jews), where it is known as the Book of Division (Ge'ez: Mets 'hafe Kufale). Jubilees is considered one of the pseudepigrapha by Protestant, Roman Catholic, and Eastern Orthodox Churches. It was well known to Early Christians, as evidenced by the writings of Epiphanius, Justin Martyr, Origen, Diodorus of Tarsus, Isidore of Alexandria, Isidore of Seville, Eutychius of Alexandria, John Malalas, George Syncellus, and George Kedrenos.
