Daniel 10:7-9

7I, Daniel, was the only one who saw the vision; those who were with me did not see it, but such terror overwhelmed them that they fled and hid themselves. 8So I was left alone, gazing at this great vision; I had no strength left, my face turned deathly pale and I was helpless.

9Then I heard him speaking, and as I listened to him, I fell into a deep sleep, my face to the ground.
