The Book of Jubilees, sometimes called Lesser Genesis (Leptogenesis), is an ancient Jewish religious work of 50 chapters (1,341 verses), 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 Roman Catholic, Eastern Orthodox, and Protestant Churches. It is also not considered canonical within Judaism outside of Beta Israel.
It was well known to Early Christians, 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.
The Book of Jubilees claims to present "the history of the division of the days of the Law, of the events of the years, the year-weeks, and the jubilees of the world" as revealed to Moses (in addition to the Torah or "Instruction") by angels while he was on Mount Sinai for forty days and forty nights. The chronology given in Jubilees is based on multiples of seven; the jubilees are periods of 49 years (seven "year-weeks"), into which all of time has been divided.
Manuscripts
Until the discovery of extensive fragments among the Dead Sea Scrolls, the earliest surviving manuscripts of Jubilees were four complete Ge'ez texts dating to the 15th and 16th centuries, and several quotations by the Church fathers such as Epiphanius, Justin Martyr, Origen as well as Diodorus of Tarsus, Isidore of Alexandria, Isidore of Seville, Eutychius of Alexandria, John Malalas, George Syncellus, and George Kedrenos. There is also a preserved fragment of a Latin translation of the Greek that contains about a quarter of the whole work. The Ethiopic texts, now numbering twenty-seven, are the primary basis for translations into English. Passages in the texts of Jubilees that are directly parallel to verses in Genesis do not directly reproduce either of the two surviving manuscript traditions. Consequently, even before the Qumran discoveries, R.H. Charles had deduced that the Hebrew original had used an otherwise unrecorded text for Genesis and for the early chapters of Exodus, one independent either of the Masoretic text or of the Hebrew text that was the basis for the Septuagint. According to one historian, the variation among parallel manuscript traditions that are exhibited by the Septuagint compared with the Masoretic text, and which are embodied in the further variants among the Dead Sea Scrolls, demonstrates that even canonical Hebrew texts did not possess any single "authorized" manuscript tradition before the Common Era. Others write about the existence of three main textual manuscript traditions (namely the Babylonian, Samarian and Pre-Masoretic "proto" textual traditions). Although the Pre-Masoretic text may have indeed been authoritative back then, arguments can be made for and against this concept.
Between 1947 and 1956, approximately 15 Jubilees scrolls were found in five caves at Qumran, all written in Hebrew. The large number of manuscripts (more than for any biblical books except for Psalms, Deuteronomy, Isaiah, Exodus, and Genesis, in descending order) indicates that Jubilees was widely used at Qumran. A comparison of the Qumran texts with the Ethiopic version, performed by James VanderKam, found that the Ethiopic was in most respects an accurate and literalistic translation.
Origins
Robert Henry Charles (1855–1931) became the first biblical scholar to propose an origin for Jubilees. Charles suggested that the author of Jubilees may have been a Pharisee and that Jubilees was the product of the midrash which had already been worked on in the Tanakh/Old Testament Books of Chronicles. With the discovery of the Dead Sea Scrolls at Qumran in 1947, Charles' Pharisaic hypothesis of the origin of Jubilees has been almost completely abandoned.
The dating of Jubilees has been problematic for biblical scholars. While the oldest extant copies of Jubilees can be assigned on the basis of the handwriting to about 100 BC, there is much evidence to suggest Jubilees was written prior to this date.
