Hebrews 1:7

“of--The Greek is rather, "In reference TO the angels." spirits--or "winds": Who employeth His angels as the winds, His ministers as the lightnings; or, He maketh His angelic ministers the directing powers of winds and flames, when these latter are required to perform His will. "Commissions them to assume the agency or form of flames for His purposes" [ALFORD]. English Version, "maketh His angels spirits," means, He maketh them of a subtle, incorporeal nature, swift as the wind. So Psa 18:10, "a cherub . . . the wings of the wind." Heb 1:14, "ministering spirits," favors English Version here. As "spirits" implies the wind-like velocity and subtle nature of the cherubim, so "flame of fire"…”

“And of the angels he saith, Who maketh his angels spirits - He gives to them an inferior name, and assigns to them a more humble office. They are mere ministers, and have not ascribed to them the name of “Son.” They have a name which implies a more humble rank and office - the name “spirit,” and the appellation of a “flame of fire.” They obey his will as the winds and the lightnings do. The “object” of the apostle in this passage is to show that the angels serve God in a ministerial capacity - as the winds do; while the Son is Lord of all. The one serves him passively, as being wholly under his control; the other acts as a Sovereign, as Lord over all, and is addressed and regarded as the…”

“Who maketh his angels - This implies, they are only creatures, whereas the Son is eternal, Heb 1:8; and the Creator himself, Heb 1:10. Spirits and a flame of fire - Which intimates not only their office, but also their nature; which is excellent indeed, the metaphor being taken from the most swift, subtle, and efficacious things on earth; but nevertheless infinitely below the majesty of the Son. Psa 104:4. Hebrews 1:8”

“1:7 This verse quotes Ps 104:4 to show that the angels are messengers or servants and, therefore, of a lesser rank than the Son, whom they serve. • In the Old Testament, angels are sometimes associated with winds and fire (see Exod 3:2; Judg 6:21; 13:16, 20; 2 Sam 22:11; Pss 18:10; 35:5), which is why angels are mentioned in connection with God’s lordship over nature.”
