The paper investigates the anti-Noachic tendencies in 2 Enoch. The analysis shows that anti-Noachic polemics in 2 Enoch are based on the «original» Noachic materials which demonstrate close parallels with the fragments of the Book of Noah found in 1 Enoch, Jubilees and the Genesis Apocryphon. The anti-Noachic debates involve a substantial rewriting of the «original» Noachic motifs and themes. The research shows that 2 Enoch contains a systematic tendency to diminish or refocus the priestly significance of the Noachic tradition. These anti-Noachic revisions take place in the midst of the sectarian debates about the sacrificial practice and the priestly succession.
