Revelation 6:15-17
6:15 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.
6:16 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,
6:17 because the great day of their wrath has come, and who is able to withstand it?”
