Hebrews 1:7
Nestle 1904 Greek New Testament · Berean Standard Bible
Καὶ πρὸς μὲν τοὺς ἀγγέλους λέγει Ὁ ποιῶν τοὺς ἀγγέλους αὐτοῦ πνεύματα καὶ τοὺς λειτουργοὺς αὐτοῦ πυρὸς φλόγα
Now about the angels He says: “He makes His angels winds, His servants flames of fire (note: Psalm 104:4 (see also LXX)).”
