"Who makes his angels winds, and his servants flames of fire."

St. Paul's Letter to the Hebrews 1:1-12

IN MANY AND VARIOUS WAYS God spoke of old to our fathers by the
prophets; but in these last days he has spoken to us by a Son, whom he
appointed the heir of all things, through whom also he created the world.
He reflects the glory of God and bears the very stamp of his nature,
upholding the universe by his word of power. When he had made purification
for sins, he sat down at the right hand of the Majesty on high,
having become as much superior to angels as the name he has obtained is
more excellent than theirs. For to what angel did God ever say, "Thou
art my Son, today I have begotten thee"? Or again, "I will be to him
a father, and he shall be to me a son"? And again, when he brings
the first-born into the world, he says, "Let all God's angels worship
him." Of the angels he says, "Who makes his angels winds, and his
servants flames of fire." But of the Son he says, "Thy throne, O God, is
for ever and ever, the righteous scepter is the scepter of thy
kingdom. Thou hast loved righteousness and hated lawlessness; therefore
God, thy God, has anointed thee with the oil of gladness beyond thy
comrades." And, "Thou, Lord, didst found the earth in the beginning, and the
heavens are the work of thy hands; they will perish, but thou remainest;
they will all grow old like a garment, like a mantle thou wilt roll
them up, and they will be changed. But thou art the same, and thy
years will never end."
