'Someone' in the Bible

At this, Daniel answered, speaking directly to the king, "Let your gifts and rewards be given to someone else. However, I'll read the writing for the king and tell him its meaning.

"I continued to observe the night vision and look! someone like the Son of Man was coming, accompanied by heavenly clouds. He approached the Ancient of Days and was presented before him.

But suddenly someone who resembled a human being touched my lips, so addressing the one who was standing in front of me, I opened my mouth and said, "Sir, I'm overwhelmed with anguish by this vision. I have no strength left.

So how can a servant of my lord talk with someone like you, sir? And as for me, there's no strength left in me, and I can hardly breathe.'
