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: መጽሃፈ 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 the Beta Israel. - Summary by Wikipedia
