Notes and References
"... The material that now appears in the Book of the Watchers is the earliest preserved instance in which Genesis 5:21-24 and 6:1-13 are combined or closely related to one another. And, though the LXX of Genesis 5:21-24 (and of 6:1-13) is much more closely tied to the biblical text, it, too, engages in some reinterpretation ... Of course, the process of reinterpretation continued into the targumim; Targum Onkelos says that God killed Enoch ..."
