This document is frequently quoted in the Testaments: cf. Sim. 5; Levi 14, 16; Judah 18; Dan 5; Naph. 4; Benj. 9. Most of these citations, however, are not to be found in the work as it has come down to us. We must therefore either assume the reference to some other books of Enoch not now extant, or rather perhaps that they are general appeals to the spirit of the book, regarded as a great fount of prophecy.
