1 Enoch 1:9
6 The high mountains will shake, the hills will be leveled, and they will melt like wax before the fire 7 The earth will be completely torn apart, and everything on it will perish, and there will be judgment upon all people. 8 But with the righteous, He will establish peace. He will protect the chosen, and mercy will be upon them. They will all belong to God, prosper, and be blessed. He will aid them, and light will shine for them, and He will make peace with them. 9 Behold! He comes with tens of thousands of His holy ones to pass judgment upon all, to annihilate all the wicked, to convict every soul of all the godless deeds they have committed, and of all the harsh words that godless sinners have spoken against Him.
Jude 1:14
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.” 16 These people are grumblers and fault-finders who go wherever their desires lead them, and they give bombastic speeches, enchanting folks for their own gain. 17 But you, dear friends—recall the predictions foretold by the apostles of our Lord Jesus Christ. 18 For they said to you, “At the end of time there will come scoffers, propelled by their own ungodly desires.” 19 These people are divisive, worldly, devoid of the Spirit.
Notes and References
"... The longest and only unambiguous quotation in the Epistle of Jude is not from an Old Testament book but rather from 1 Enoch. There are a couple of Old Testament allusions in the Jude text. Enoch is acknowledged to be “seventh from Adam” (14), and, according to the Old Testament, counting inclusively, he is. The image of God coming with his angelic hosts (14) is drawn from Deuteronomy 33:2 ... This is a colorful metaphorical description of the theophany at Sinai. The “holy ones” probably are angels, though this is less than certain because “holy ones” in the ensuing verse (33:3) clearly refers to God’s people. Nevertheless, the language is picked up by 1 Enoch 1:9 and then cited here in Jude to conjure up the divine court coming for final judgment ..."
