1 Enoch 60:7
6 On that day, two great monsters were separated, a female monster named Leviathan, to dwell in the depths of the ocean over the springs of waters. 7 The male is named Behemoth, who with his chest occupies a desolate wilderness named Dûidâin, east of the garden where the chosen and righteous dwell, where my grandfather was taken up, the seventh from Adam, the first man whom the Lord of Spirits created. 8 I pleaded with the other angel to show me the power of these monsters, how they were separated on one day and thrown, one into the depths of the sea, and the other into the dry land of the wilderness.
Jude 1:14
12 These men are dangerous reefs at your love feasts, feasting without reverence, feeding only themselves. They are waterless clouds, carried along by the winds; autumn trees without fruit—twice dead, uprooted; 13 wild sea waves, spewing out the foam of their shame; wayward stars for whom the utter depths of eternal darkness have been reserved. 14 Now Enoch, the seventh in descent beginning with Adam, even prophesied of them, saying, “Look! The Lord is coming with thousands and thousands of his holy ones, 15 to execute judgment on all, and to convict every person of all their thoroughly ungodly deeds that they have committed, and of all the harsh words that ungodly sinners have spoken against him.”

"... This Mesopotamian theological propaganda has importance for the present study. Babylonian scribal tradition held that the seventh antediluvian king, Enmeduranki, had received divine knowledge from the gods. Given the similarities between the Sumerian King List and the genealogies in Genesis 4–5, scholars have noted that the seventh patriarch in the period before the flood in the biblical material was Enoch (Genesis 5:23–24). Enoch was the seventh from Adam (Jude 14), the one who was taken from earth to the heavenly realm. This correspondence was one basis for the authority of Enoch in apocalyptic Jewish literature in the Second Temple period. Enoch, the seventh from Adam, had access to divine knowledge ..."
