Daniel 10:16-19

16And, behold, one in the likeness of the sons of men touched my lips: then I opened my mouth, and spake and said unto him that stood before me, O my lord, by reason of the vision my sorrows are turned upon me, and I retain no strength. 17For how can the servant of this my lord talk with this my lord? for as for me, straightway there remained no strength in me, neither was there breath left in me.

18Then there touched me again one like the appearance of a man, and he strengthened me. 19And he said, O man greatly beloved, fear not: peace be unto thee, be strong, yea, be strong. And when he spake unto me, I was strengthened, and said, Let my lord speak; for thou hast strengthened me.
