Daniel 10:16-17

And behold, one who resembled the sons of men touched my lips. Then I opened my mouth and spoke and said to him who was standing before me, “O my lord, because of the vision anguish has come upon me, and I have retained no strength. For how can such a [weakened] servant of my lord talk with such [a being] as my lord? For now there remains no strength in me, nor has any breath been left in me.”
