was the book of enoch in the septuagint
Although evidently widely known during the development of the Hebrew Bible canon, 1 Enoch was excluded from both the formal canon of the Tanakh and the typical canon of the Septuagint and therefore, also from the writings known today as the Deuterocanon. One possible reason for Jewish rejection of the book might be the textual nature of several early sections of the book that make use of material from the Torah; for example, 1 En 1 is a midrash of Deuteronomy 33. The content, particularly detailed descriptions of fallen angels, would also be a reason for rejection from the Hebrew canon at this period -- as illustrated by the comments of Trypho the Jew when debating with Justin Martyr on this subject: ``The utterances of God are holy, but your expositions are mere contrivances, as is plain from what has been explained by you; nay, even blasphemies, for you assert that angels sinned and revolted from God.''
