'Dignity' in the Bible

For to which of the angels did the Father ever say,“You are My Son,Today I have begotten (fathered) You [established You as a Son, with kingly dignity]”?And again [did He ever say to the angels],“I shall be a Father to HimAnd He shall be a Son to Me”?

But to which of the angels has the Father ever said,“Sit at My right hand [together with me in royal dignity],Until I make your enemiesA footstool for your feet [in triumphant conquest]”?
