Numbers 24:16, "He hath said, which heard the words of God, and knew the knowledge of the most High, which saw the vision of the Almighty, falling into a trance, but having his eyes open:"
When in "vision" their eyes will be open
4. Daniel 10:17, "For 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 is there breath left in me."
When in "vision" a true Prophet will NOT breath. "Inspiration" = God Breathed, Therefore, since the Almighty is breathing through the Prophet communicating His Truth, the Prophet has no need to breath
5. Daniel 10:17, "For 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 is there breath left in me."
