2 Esdras 6:15

15 while the voice is speaking, don't be afraid. The message will be about the end of the world, and the foundations of the world will understand

2 Esdras 6:15 In-Context

13 "Stand up," he said, "and you will hear a very loud voice.
14 If the place where you are standing is violently shaken
15 while the voice is speaking, don't be afraid. The message will be about the end of the world, and the foundations of the world will understand
16 that the voice is speaking about them. They will tremble and quake because they know that they will undergo a change when the end comes."
17 When he said this, I stood up and listened. I heard a voice that sounded like a roaring river.
