2 Esdras 6:15

15 while the voice is speaking, do not be terrified; because the word concerns the end, and the foundations of the earth will understand

2 Esdras 6:15 In-Context

13 He answered and said to me, "Rise to your feet and you will hear a full, resounding voice.
14 And if the place where you are standing is greatly shaken
15 while the voice is speaking, do not be terrified; because the word concerns the end, and the foundations of the earth will understand
16 that the speech concerns them. They will tremble and be shaken, for they know that their end must be changed."
17 When I heard this, I got to my feet and listened; a voice was speaking, and its sound was like the sound of mighty waters.
