1 Enoch 5:4
2 And all His works continue year after year forever, and all the tasks they perform for Him, and their tasks do not change, but happen just as God has decreed. 3 And see how the sea and the rivers also fulfill their tasks unchangingly according to His commands. 4 But you have not remained faithful, nor have you obeyed the Lord's commandments. Instead, you have turned away and spoken arrogantly and harshly with your impure mouths against His greatness. Oh, you stubborn-hearted, you will find no peace. 5 Therefore, you will curse your own days, and the years of your life will vanish, and the years of your doom will increase in eternal condemnation, and you will find no mercy.
Jude 1:16
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.”
Notes and References
"... Jude 15 repeats the same terms for rhetorical effect: 'all' (four times), 'impious' (three times) and 'judge/convict' (two times). In all probability, the reference to God coming with the angels in Zechariah 14:5 (and possibly Deuteronomy 33:2) is in the background here. In the New Testament the angels are seen as those who not only save (harvest) the redeemed, but also cast the wicked into the fiery furnace (Mark 13:27; 2 Thessalonians 1:7; Matthew 13:41, 49-50) - thev are the executors of the final verdict pronounced by Jesus the Lord. This judgment will involve convicting the godless of their sin, that is, not merely condemning them but making it so that they will see the error of their ways. These impious men dared to speak "hard words," that is, words of defiance or resistance to God's law or word or possibly (compare 1 Enoch 5.4) slanderous words against God's word ..."
