'Sit at My Right Hand' in the Bible

A Psalm of David.The Lord says to my Lord:“Sit at My right handUntil I make Your enemies a footstool for Your feet.”

‘The Lord said to my Lord,“Sit at My right hand,Until I put Your enemies beneath Your feet”’?

David himself said in the Holy Spirit,‘The Lord said to my Lord,“Sit at My right hand,Until I put Your enemies beneath Your feet.”’

For David himself says in the book of Psalms,‘The Lord said to my Lord,“Sit at My right hand,

For it was not David who ascended into heaven, but he himself says:‘The Lord said to my Lord,“Sit at My right hand,

But to which of the angels has He ever said,“Sit at My right hand,Until I make Your enemiesA footstool for Your feet”?
