'Right Hand' in the Bible

Who being the brightness of his glory, and the express image of his person, and sustaining all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the majesty on high,

But to which of the angels did he ever say, Sit at my right hand, till I make thine enemies thy footstool?

for ever sat down at the right hand of God, From thenceforth expecting till his enemies be made his footstool.
