The Book of Jubilees (Hebrew: ספר היובלים Sefer haYovelim), sometimes called the Lesser Genesis (Leptogenesis), is an ancient Jewish religious work, considered one of the Pseudepigrapha by most Roman Catholic, Eastern Orthodox and Protestant Christians. It was well known to Early Christian writers in the East and the West, as well as by the Rabbis. Later it was so thoroughly suppressed that no complete Hebrew, Greek or Latin version has survived.It is considered canonical for the Ethiopian Orthodox Church, where it is known as the Book of Division (Ge'ez: Mets'hafe Kufale). In the modern scholarly view, it reworks material found in the biblical books of Genesis and Exodus in the light of concerns of some 2nd century BC Jews.
