Hebrews 1:10–14 (ESV)
“You, Lord, laid the foundation of the earth in the beginning,
and the heavens are the work of your hands;
 they will perish, but you remain;
they will all wear out like a garment,
 like a robe you will roll them up,
like a garment they will be changed.
But you are the same,
and your years will have no end.”
 And to which of the angels has he ever said,
“Sit at my right hand
until I make your enemies a footstool for your feet”?
 Are they not all ministering spirits sent out to serve for the sake of those who are to inherit salvation?
