Matthew 26:64

It was not fit that the Lord should answer the High Priest's adjuration as though under compulsion, wherefore He neither denied nor confessed Himself to be the Son of God. For he was not worthy to be the object of Christ's teaching, therefore He does not instruct him, but taking up his own words retorts them upon him. This sitting of the Son of Man seems to me to denote a certain regal security; by the power of God, Who is the only power, is He securely seated to Whom is given by His Father all power in heaven as in earth. And there will come a time when the enemies shall see this establishment. Indeed this has begun to be fulfilled from the earliest time of the dispensation; for the disciples saw Him rising from the dead, and thereby saw Him seated on the right hand of power. Or, In respect of that eternity of duration which is with God, from the beginning of the world to the end of it is but one day; it is therefore no wonder that the Saviour here says, Shortly, signifying that there is but short time before the end come. He prophesies moreover, that they should not only see Him sitting at the right hand of power, but also coming in the clouds of heaven. These clouds are the Prophets and Apostles, whom He commands to rain when it is required, they are the clouds that pass not away, but bearing the image of the heavenly, (1 Cor. 15:49.) are worthy to be the throne of God, as heirs of God, and joint-heirs with Christ. (Rom. 8:17.)

"But He said, Thou hast said. Nevertheless I say unto you, Hereafter shall ye see the Son of Man sitting at the right hand of power, and coming in the clouds. Then the high priest rent his clothes, saying, He hath spoken blasphemy." And this he did to add force to the accusation, and to aggravate what He said, by the act. For since what had been said moved the hearers to fear, what they did about Stephen, stopping their ears, this high priest doth here also. And yet what kind of blasphemy was this? For indeed before He had said, when they were gathered together, "The Lord said unto my Lord. Sit Thou on my right hand," and interpreted the saying, and they dared say nothing, but held their peace, and from that time forth gainsaid Him no more. Why then did they now call the saying a blasphemy? And wherefore also did Christ thus answer them? To take away all their excuse, because unto the last day He taught that He was Christ, and that He sitteth at the right hand of the Father, and that He will come again to judge the world, which was the language of one manifesting His full accordance with the Father.
