Book of Jubilees

The Book of Jubilees, often referred to as Lesser Genesis (Leptogenesis), is an ancient Jewish religious text comprising 50 captivating chapters. It holds a special place as canonical scripture within the Ethiopian Orthodox Church and among Beta Israel (Ethiopian Jews), where it is known as the Book of Division (Geez መጽሃፈ ኩፋሌ Metshafe Kufale). While it is classified as pseudepigrapha by Protestant, Roman Catholic, and Eastern Orthodox Churches, it is not recognized as canonical in mainstream Judaism outside of the Beta Israel community. - Summary by Wikipedia
