Matthew 26:63

And the high priest said unto him, I adjure thee by the living God, that thou tell us whether thou art the Christ, the Son of God.

That was the very instant toward which Christ had unerringly moved from the very first moment of his public life to that precise moment. At last, there was no danger of being misunderstood as a seditionist; there, before the assembled elders of his nation, in solemn convocation, before the sacred Sanhedrin, the high priest placed the Christ upon judicial oath, lifting his hands over his own head after the customs of Israel, and intoning the solemn oath, "I adjure thee by the living God, tell us whether thou art the Christ," the Son of God. The answer of Jesus as recorded by Mark (Mark 14:62), while more satisfactory to English ears, is not so dramatic as Matthew's before the Hebrew court where it was delivered. Both accounts record the dramatic shock with which Jesus' words were received.

From Mark (Mark 14:62): "And Jesus said, I am, and ye shall see the Son of Man, sitting at the right hand of power and coming with the clouds of heaven."
