Mark 14:62

And Jesus said, I am
That is, the Son of God; in proof of which he adds,

and ye shall see the son of man sitting on the right hand of power;
that is, of God, who is all power, the Lord God Almighty:

and coming in the clouds of heaven;
either at the destruction of Jerusalem, or at the last day, referring to the prophecy in ( Daniel 7:13 ) ; (See Gill on Matthew 26:64).
