Collection of reasons is sanctified to the study of early judaic apocalyptic works existing in Slavic tradition. These "secret books", such, as the "Book of Enoch Just", "Revelation of Abraham" and "Лествица of Jacob", saved only in Slavic translations, narrate about events, preceding to creation of the visible world and that will happen with humanity at the end of times, after doomsday. They link exactly апокалиптику of the Second Temple and later judaic mystic flows - Celestial Halls (Хейхалот) and Divine Chariot (Меркава). Analysing these texts, an author opens their value in forming of symbolics of early judaic mysticism. In these books told about ascension of righteous man on skies and his transforming in an immortal celestial creature by means of the so-called "dew of reviving" are oils of Divine plenty, to outflowing from Tree Life. Apocryphal histories of celestial ascension and transforming of such biblical patriarchs, as Enoch, Jacob and Abraham, played a major role a transition from an apocalyptic symbolics to the unique теофанической vividness of later judaic mysticism.
