Daniel 10:7-9

7And I, Daniel, alone saw the vision [of this heavenly being], for the men who were with me did not see the vision; nevertheless, a great panic overwhelmed them, so they ran away to hide themselves.

8So I was left alone and saw this great vision; yet no strength was left in me, for my normal appearance turned to a deathly pale, and I grew weak and faint [with fright].

9Then I heard the sound of his words; and when I heard the sound of his words, I fell on my face in a deep sleep, with my face toward the ground.
