The term Son of Man
most likely refers to the figure seen in Daniel 7:13–14. There, the Son of Man (also translated as the human one
) is a Messiah figure who comes to the Lord (the Ancient of Days
) with clouds surrounding him. This person is given dominion over all creation. Elsewhere in the Bible, the Lord himself is depicted as riding on the clouds (e.g., Isaiah 19:1) and thus we see that Daniel somehow considers the Son of Man to be like the Lord: the Son of Man is human in appearance and yet also divine. This title, therefore, is a very fitting title for Jesus to use in describing his ministry since he is divine and human and he has come to establish the kingdom of God on earth (Mark 1:15).
31 And he began to teach them that the Son of Man must suffer many things and be rejected by the elders and the chief priests and the scribes and be killed, and after three days rise again.
