"Jubilees" covers much of the same ground as "Genesis", but often with additional detail, and addressing Moses in the second person as the entire history of creation, and of Israel up to that point, is recounted in divisions of 49 years each, or "Jubilees". The elapsed time from the creation, up to Moses receiving the scriptures upon Sinai during the Exodus, is calculated as fifty Jubilees, less the 40 years still to be spent wandering in the desert before entering Canaan – or 2,410 years.
