Da 8:16  And I heard a man's voice between the banks of Ulai, which called, and said, Gabriel, make this man to understand the vision.

Da 9:21,22  Yea, whiles I was speaking in prayer, even the man Gabriel, whom I had seen in the vision at the beginning, being caused to fly swiftly, touched me about the time of the evening oblation. 

22  And he informed me, and talked with me, and said, O Daniel, I am now come forth to give thee skill and understanding.
