Heb 1:10-14

and:

“At the beginning, O Lord, you established the earth,

and the heavens are the works of your hands.

They will perish, but you remain;

and they will all grow old like a garment.

You will roll them up like a cloak,

and like a garment they will be changed.

But you are the same, and your years will have no end.”

But to which of the angels has he ever said:

“Sit at my right hand

until I make your enemies your footstool”?

Are they not all ministering spirits sent to serve, for the sake of those who are to inherit salvation?
