"I saw in the night visions, and, behold, one like the Son of man came with the clouds of heaven, and came to the Ancient of days, and they brought him near before him." (DAN 7:13)
1) The "one like the Son of man" is Jesus, Who was the only man wholly obedient to God, as explained in the next verse, "there was given him dominion, and glory, and a kingdom, that all people, nations, and languages, should serve him: his dominion is an everlasting dominion, which shall not pass away, and his kingdom that which shall not be destroyed." (DAN 7:14)
2) I must assume the Ancient of days is God the Father, since the Son of Man is brought before Him... however, this Ancient of Days fits John's description of Christ in Revelation, "His head and his hairs were white like wool, as white as snow; and his eyes were as a flame of fire;" (REV 1:13-14)
3) "They" are the ones who go to and fro in the clouds of heaven doing the Father's will. They are the angels, the Sons of God, who minister to the Elect of heavens and earth, and who wage unceasing war against the enemy,
"And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other." (MATT 24:31)
"[i]the Son of man came [b]with the clouds of heaven[/b][/i], and came to the Ancient of days, [i]and [b]they[/b] brought him near before him.[/i]" (DAN 7:13)
