Book of Jubilees

Jubilees, sometimes called Little Genesis or Lesser Genesis and known at Qumran as the Book of the Divisions of the Times, runs to fifty chapters. It is not a commentary. It is the narrative of Genesis 1 to Exodus 14 told again from the beginning, with material added, removed and rearranged, and presented throughout as dictation from an Angel of the Presence to Moses during the forty days on Sinai. The claim of the frame is that this account, not simply the one in the Torah, is what Moses received.

The rewriting has consistent aims. It closes the awkward gaps in Genesis: Cain's wife is named, so are the wives of the patriarchs, and the sons of Noah divide the earth by lot in a passage that becomes a charter for Israel's title to Canaan. It removes what is embarrassing. Abraham is a monotheist from youth who burns an idol temple. Above all it dates everything, placing each event in a numbered jubilee, week and year, so that sacred history acquires a continuous chronology it does not have in Genesis.

It also introduces Mastema, prince of the hostile spirits, whose demons are reduced to a tenth after the Flood at Noah's plea, and who prompts the testing of Abraham, so that the command to sacrifice Isaac originates in a challenge rather than in God alone. The festivals are pushed back into the patriarchal age: Shavuot is kept by Noah, Sukkot founded by Abraham. And the law is stricter than the Torah's. Sabbath-breaking and intermarriage carry death, and the rape of Dinah becomes the ground of an absolute prohibition on giving daughters to gentiles.

The calendar of Jubilees is not decoration. Its year has 364 days, in four quarters of thirteen weeks, each quarter of three months of thirty, thirty and thirty-one days. The arithmetic is the point: 364 divides by seven exactly, so every date falls on a fixed weekday, year after year. No festival can drift onto a Sabbath and force a compromise between two obligations.

Against this the book attacks lunar reckoning directly, warning that those who observe the moon will disturb the seasons and eat unclean things and keep the feasts on the wrong days. That is a charge aimed at the temple in Jerusalem, whose calendar was lunar-solar with months set by observation of the new moon and intercalation to hold the year to the seasons.

The consequence is a permanent schism in practice rather than a theoretical disagreement. A community keeping the 364-day year celebrates Passover and the Day of Atonement on days when the temple is doing something else, and the temple's Day of Atonement falls on an ordinary day for them. Shared worship becomes impossible without one side conceding. The same 364-day calendar appears in the Astronomical Book of 1 Enoch and in calendrical texts from Qumran, which is one reason the Qumran community's sectarian separation is usually read as calendrical as well as priestly and political.

Jubilees never explains how a 364-day year is kept in step with an actual solar year of about 365 and a quarter days. No intercalation scheme is given, and whether its holders used one, and what it was, remains unresolved. Some scholars propose a periodic added week; the text itself is silent, and the silence is genuine rather than a gap in the manuscripts.

Roughly fifteen manuscripts of Jubilees were recovered from five of the Qumran caves between 1947 and 1956, all in Hebrew. That count is high. Only a handful of biblical books are represented by more copies, and the comparison is the strongest available evidence that the community treated Jubilees as authoritative rather than as edifying reading. The Damascus Document reinforces it by citing the book by name and directing the reader to it for exact reckoning of Israel's times of blindness, one of the rare instances of one Second Temple text explicitly commending another.

Transmission thereafter is fragmentary everywhere except Ethiopia. The Hebrew original is lost apart from the cave fragments. A Greek version is known only through quotations in Christian chronographers. A Latin translation survives for about a quarter of the work, and Syriac writers preserve scattered references. The complete text exists only in Geez, in some twenty-seven manuscripts, and every modern translation rests on it. Where the Hebrew fragments overlap the Geez, the agreement is close, which gives reasonable confidence that the Ethiopic represents the ancient work.

Dating rests on internal evidence. The book knows the Hellenising crisis and the resistance to it, shows no knowledge of the Hasmonean priest-kings at their height, and depends on parts of 1 Enoch; most scholars place it around 160 to 150 BCE, some slightly earlier.

Mainstream Judaism and the Catholic, Orthodox and Protestant churches assign it no scriptural status. The Ethiopian Orthodox Tewahedo Church and the Eritrean Orthodox Tewahedo Church receive it as canonical, and Beta Israel tradition holds it likewise, so that a book excluded everywhere else has been read as scripture continuously in the Horn of Africa.
