English Summary: These "commencements" are those of a research program initiated by the Ecole Biblique et archeologique francaise in Jerusalem. The Bible in its Traditions series aims to bring together translations of the major versions of Scripture, their philological and historical annotations, and a systematic exploration of their religious and cultural interpretations over the centuries. It is a question of reinventing the model of the multilingual Bible. Editing Scripture in the 21st century, in fact, can no longer consist of printing a single text-be it the traditional version of a particular confession or the reconstituted original text, more scientific than the traditional text. The Dead Sea Scrolls and the comparative history of the Hebrew and Greek Scriptures have restored the Bible''s status as a polyphonic text, received in diverse and interrelated faith communities. Far from being a star mysteriously fallen from heaven, the Holy Book crosses history not only in various manuscripts, but also through theological treatises, liturgical performances, literary and artistic works, and music and film. French Description: Ces commencements sont ceux d''un programme de recherches ouvert par l''Ecole biblique et archeologique francaise de Jerusalem. La Bible en ses Traditions vise a rassembler sur un meme support les traductions des versions majeures des Ecritures, leurs annotations philologiques et historiques, et une exploration systematique de leurs interpretations religieuses et culturelles au fil des siecles. Il s''agit de reinventer le modele de la Bible polyglotte. Editer les Ecritures au 21e siecle, en effet, ne peut plus consister a imprimer un texte unique - fut-il la version traditionnelle d''une confession particuliere ou le texte original reconstitue, plus scientifique que le texte traditionnel. Les manuscrits de la mer Morte, l''histoire comparee des Ecritures en hebreu et en grec, ont rendu a la Bible son statut de texte polyphonique, recu en communautes croyantes aussi diverses qu''interreliees. Loin d''etre un meteore mysterieusement tombe du ciel, le Livre saint traverse l''histoire non seulement dans des manuscrits varies, mais aussi au fil de traites theologiques, de performances liturgiques, d''oeuvres litteraires et artistiques, musicales et cinematographiques.
