1 Enoch 2:1
1 Observe everything that occurs in the heaven, how the celestial bodies do not alter their paths, and the luminaries in the sky, how they all rise and set orderly, each in its own season, without deviating from their assigned courses. 2 Look at the earth, and pay attention to the things that unfold from beginning to end, how consistent they are, how nothing on earth changes, how all of God’s works appear to you. 3 Observe the summer and winter, how the entire earth is filled with water, and how clouds, dew, and rain cover it.
Jude 1:12
10 But these men do not understand the things they slander, and they are being destroyed by the very things that, like irrational animals, they instinctively comprehend. 11 Woe to them! For they have traveled down Cain’s path, and because of greed have abandoned themselves to Balaam’s error; hence, they will certainly perish in Korah’s rebellion. 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.
Notes and References
"... The influence of 1 Enoch on Jude can be briefly summarized: 1) Jude cites 1 Enoch 1:9 to demonstrate that it had been prophesied that “the Lord” (here understood as Christ) would come to judge the ungodly. The quotation is introduced as a prophecy in precisely the language Matthew uses to cite Isaiah (Matthew 15:7). This is, in fact, the only formal citation in the Letter of Jude. Furthermore, Enoch is identified in no casual way, as though Jude were merely citing a convenient passage; rather, Enoch is designated as “the seventh from Adam,” and thus given a special place as an antediluvian figure who spoke at a symbolic point in the created order, a man who lived before the flood, amidst the immoral generation that, for Jude, corresponds to his own. 2) Jude 6 makes reference to the fall of the angels as a paradigmatic sin. Such a reference need not depend directly on 1 Enoch, for Genesis 6:1–4 was itself widely interpreted as referring to the Fall of the Watchers; but 1 Enoch 6–16 was the earliest and most influential version of this mythic event, and Jude’s description evinces enough terminological similarities to 1 Enoch that we may safely presume that this was his source. 3) In Jude 12–13 the opponents are depicted as “waterless clouds, fruitless trees, wild waves, wandering stars” - images apparently drawn from 1 Enoch 2:1–5:4 and 1 Enoch 80:2–8. Other allusions to Enochic language and motifs have been detected in Jude, but the current examples are sufficient to demonstrate that “1 Enoch 1–5 and related passages in the Enoch literature lie at the foundation of Jude’s exegetical work” ..."
