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 Beta Israel (Ethiopian Jews), where it is known as the Book of Division (Ge'ez: መጽሐፈ ኩፋሌ Mets'hafe Kufale). Jubilees is considered one of the pseudepigrapha by Protestant, Roman Catholic, and Eastern Orthodox Churches. It is also not considered canonical within Judaism outside of Beta Israel.
It was well known to Early Believers, 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. The text was also utilized by the community that originally collected the Dead Sea Scrolls. No complete Greek or Latin version is known to have survived, but the Ge'ez version has been shown to be an accurate translation of the versions found in the Dead Sea Scrolls.
