The Damascus Document is an ancient Hebrew text that is one of the longest, oldest, and most important of the ancient scrolls found near Khirbet (ruins of) Qumran, usually referred to collectively as the Dead Sea Scrolls for the proximity of the Qumran settlement and eleven nearby caves to the Dead Sea. Its oldest parts originate in the mid- to late second century BCE. While the earliest discovery of the Dead Sea Scrolls occurred in 1947, the Qumran Damascus Document fragments were discovered in 1952 (but not published in full until 1996), mainly in what is designated as Qumran Cave Four (some ten manuscripts altogether). However, it is unique in that two manuscripts (MS A and MS B) containing parts and variations of the same text were discovered much earlier, in 1896 (and published in 1910), among the discarded texts of the Cairo Geniza, the latter being written in the tenth-eleventh centuries CE. Together, the manuscripts of the Damascus Document, both ancient and medieval, are an invaluable source for understanding many aspects of ancient Jewish (and before that Israelite) history, theology, sectarian ideology, eschatology, liturgy, law, communal leadership, canon formation, and practice. Central to the structure of the overall text, is the intersection of law, both what we would call “biblical” (or biblically derived) and “communal,” and narrative/historical admonitions, perhaps modeled after a similar division the biblical book of Deuteronomy. A suitable characterization of the Damascus Document, to which we will repeatedly return, could be “bringing the Messiah through law.” Because of the longevity of its discovery, translation, publication, and debated interpretation, there is a long history of modern scholarship devoted to this ancient text.
