“Then they will see

The Son of Man

Coming in a cloud

With power

And great glory.”

 

καὶ τότε ὄψονται τὸν Υἱὸν τοῦ ἀνθρώπου ἐρχόμενον ἐν νεφέλῃ μετὰ δυνάμεως καὶ δόξης πολλῆ

 

Luke indicated that Jesus said that then they would see (καὶ τότε ὄψονται) the Son of Man (τὸν Υἱὸν τοῦ ἀνθρώπου) coming in a cloud (ἐρχόμενον ἐν νεφέλῃ) with power (μετὰ δυνάμεως) and great glory (καὶ δόξης πολλῆ).  This is almost word for word in Matthew, chapter 24:30, and in Mark, chapter 13:26.  Mark said that they would all see or experience the Son of Man (καὶ τότε ὄψονται τὸν Υἱὸν τοῦ ἀνθρώπου) coming in the clouds (ἐρχόμενον ἐν νεφέλαις) with his great power (μετὰ δυνάμεως πολλῆς) and glory (καὶ δόξης).  Matthew indicated that Jesus had an introductory comment that the sign of the Son of Man would appear in the heavens (καὶ τότε φανήσεται τὸ σημεῖον τοῦ Υἱοῦ τοῦ ἀνθρώπου ἐν οὐρανῷ).  Then all the tribes or races of people on the earth would mourn or lament (καὶ τότε κόψονται πᾶσαι αἱ φυλαὶ τῆς γῆς).  After these phrases, then came the common element that they would all see or experience the Son of Man (καὶ ὄψονται τὸν Υἱὸν τοῦ ἀνθρώπου) coming on the clouds of heaven (ἐρχόμενον ἐπὶ τῶν νεφελῶν τοῦ οὐρανοῦ) with his power (μετὰ δυνάμεως) and great glory (καὶ δόξης πολλῆς).  The clouds were the common place where theophanies in the Old Testament occurred, as Yahweh often appeared in a cloud on a mountain.  The Son of Man is a reference to Jesus himself as a Hebrew Messianic figure.  What do you know about the Second Coming of Jesus?
