'Coming on the Clouds' in the Bible

And at that time the sign of the Son of Man [coming in His glory] will appear in the sky, and then all the tribes of the earth [and especially Israel] will mourn [regretting their rebellion and rejection of the Messiah], and they will see the Son of Man coming on the clouds of heaven with power and great glory [in brilliance and splendor].

Jesus said to him, “You have [in fact] said it; but more than that I tell you [regardless of what you do with Me now], in the future you will see [Me revealed as] the Son of Man seated at the right hand of Power, and coming on the clouds of heaven.”

Jesus said, “I am; and you will [all] see the Son of Man seated [with authority] at the right hand of Power (the Father), and coming with the clouds of heaven.”
