'Sitting at the Right Hand' in the Bible

Jesus saith to him, Thou hast spoken [the fact]. Moreover I tell you, hereafter ye shall see the Son of man sitting at the right hand of power, and coming in the clouds of heaven.

Then said Jesus, I am. And ye shall see the Son of man sitting at the right hand of power, and coming with the clouds of heaven.

And entering into the sepulchre, they saw a young man sitting at the right hand, clothed in a white robe; and they were greatly terrified.
