“But Jesus was silent.

Then the high priest

Said to him.

‘I put you under oath

Before the living God!

Tell us!

If you are the Christ,

The Messiah,

The Son of God?’

Jesus said to him.

‘You have said so.

But I tell you!

From now on

You will see

The Son of Man

Seated at the right hand

Of Power.

He will be coming

On the clouds of heaven.’”

ὁ δὲ Ἰησοῦς ἐσιώπα. καὶ ὁ ἀρχιερεὺς εἶπεν αὐτῷ Ἐξορκίζω σε κατὰ τοῦ Θεοῦ τοῦ ζῶντος ἵνα ἡμῖν εἴπῃς εἰ σὺ εἶ ὁ Χριστὸς ὁ Υἱὸς τοῦ Θεοῦ.

λέγει αὐτῷ ὁ Ἰησοῦς Σὺ εἶπας· πλὴν λέγω ὑμῖν, ἀπ’ ἄρτι ὄψεσθε τὸν Υἱὸν τοῦ ἀνθρώπου καθήμενον ἐκ δεξιῶν τῆς δυνάμεως καὶ ἐρχόμενον ἐπὶ τῶν νεφελῶν τοῦ οὐρανοῦ.

This is almost word for word in Mark, chapter 14:61-62.  In Luke, chapter 22:67-69, there is something similar, but there is nothing like this in John, chapter 18.  Matthew said that Jesus was originally silent (ὁ δὲ Ἰησοῦς ἐσιώπα).  Then the high priest Caiaphas said to Jesus (καὶ ὁ ἀρχιερεὺς εἶπεν αὐτῷ) that he was going to put him under oath according to the living God (Ἐξορκίζω σε κατὰ τοῦ Θεοῦ τοῦ ζῶντος).  Caiaphas told Jesus to tell everyone there (ἵνα ἡμῖν εἴπῃς) whether he was the Christ, the Messiah, the Son of God (εἰ σὺ εἶ ὁ Χριστὸς ὁ Υἱὸς τοῦ Θεοῦ).  This was a strongly worded theological statement.  Then Jesus replied to Caiaphas, the high priest (λέγει αὐτῷ ὁ Ἰησοῦς), that he had said so (Σὺ εἶπας).  Then Jesus gave him a warning with a solemn pronouncement (πλὴν λέγω ὑμῖν).  He told him that from now on (ἀπ’ ἄρτι), he would see the Son of Man seated at the right hand of the Power, Yahweh, or God, the Father (ὄψεσθε τὸν Υἱὸν τοῦ ἀνθρώπου καθήμενον ἐκ δεξιῶν τῆς δυνάμεως), coming on the clouds of heaven (καὶ ἐρχόμενον ἐπὶ τῶν νεφελῶν τοῦ οὐρανοῦ).  Jesus gave a strong theological response that the end times were near when the Son of Man would appear on a cloud.
