Daniel 10:7-9

7And I, Daniel, alone saw the vision, for the men who were with me did not see the vision, but a great trembling fell upon them, and they fled to hide themselves.

8So I was left alone and saw this great vision, and no strength was left in me. My radiant appearance was fearfully changed, and I retained no strength.

9Then I heard the sound of his words, and as I heard the sound of his words, I fell on my face in deep sleep with my face to the ground.
