Here the editor simply changed the name Noah in the context before him into Enoch, for the statement is based on Gen. 5:32, and Enoch lived only 365 years. Chapters 6-11 are clearly from the same source; for they make no reference to Enoch, but bring forward Noah (10:1) and treat of the sin of the angels that led to the flood, and of their temporal and eternal punishment. This section is compounded of the Semjaza and Azazel myths, and in its present composite form is already presupposed by 1 Enoch 88-90. Hence these chapters are earlier than 166 B.C. Chapters 106-107 of the same book are probably from the same source; likewise 54:7-55:2, and Jubilees 7:20-39, 10:1-15. In the former passage of Jubilees the subject-matter leads to this identification, as well as the fact that Noah is represented as speaking in the first person, although throughout Jubilees it is the angel that speaks. Possibly Eth. En. 41:3-8, 43-49, 59 are from the same work. The book may have opened with Eth. En. 106-107 On these chapters may have followed Eth. En. 6-11., 65-69:25, 60, 41:3-8, 43-44, 54:7-55:2; Jubilees 7:26-39, 10:1-15.
