'Son of Man' in the Bible

“I kept looking in the night visions,And behold, with the clouds of heavenOne like a Son of Man was coming,And He came up to the Ancient of DaysAnd was presented before Him.

So he came near to where I was standing, and when he came I was frightened and fell on my face; but he said to me, “Son of man, understand that the vision pertains to the time of the end.”
