1 Enoch 62:3
2 The Lord of Spirits seated him on the throne of His glory, and the spirit of righteousness was poured out upon him. The words from his mouth slay all sinners, and all the unrighteous are destroyed from his presence. 3 On that day, all the kings, the mighty, the exalted, and those who hold the earth will stand, and they shall see and recognize how he sits on the throne of his glory, and how righteousness is judged before him, and no false word is spoken before him. 4 Pain will come upon them as upon a woman in childbirth, when her child enters the birth canal, and she feels the agony of delivery. 5 One group will look at another in terror, their faces will fall, and pain will seize them when they see the Son of Man sitting on the throne of his glory. 6 The kings, the mighty, and all who possess the earth shall bless, glorify, and extol him who reigns over all, who was hidden.
Revelation 6:15
12 Then I looked when the Lamb opened the sixth seal, and a huge earthquake took place; the sun became as black as sackcloth made of hair, and the full moon became blood red; 13 and the stars in the sky fell to the earth like a fig tree dropping its unripe figs when shaken by a fierce wind. 14 The sky was split apart like a scroll being rolled up, and every mountain and island was moved from its place. 15 Then the kings of the earth, the very important people, the generals, the rich, the powerful, and everyone, slave and free, hid themselves in the caves and among the rocks of the mountains. 16 They said to the mountains and to the rocks, “Fall on us and hide us from the face of the one who is seated on the throne and from the wrath of the Lamb, 17 because the great day of their wrath has come, and who is able to withstand it?”
Notes and References
"... The combination of four elements in Revelation and the Book of Parables [1 Enoch] is without parallel in other literature: (a) the holders of power (especially “kings” and classes of the wealthy; compare Revelation 19:18) who (b) cower in fear (c) before the throne of God which (d) is also occupied by or associated with the Lamb / Son of Man (Book of Parables). While the text of Revelation alludes to Isaiah 2:19–21 and Hosea 10:6, and 1 Enoch 62:3–5 draws on the image of the woman in labor in Isaiah 13:8, the possibility of a connection between the two sources cannot be discounted, though it is difficult to argue that the connection is immediate ..."
