Hebrews 1:7

An Understandable Version (2005 edition)

But God said [this] about the angels [Psa. 104:4 LXX], “He [i.e., God] makes His angels to be [like] winds and His servants [like] flames of fire.” [Note: The idea is probably that angels obediently serve God’s purpose similar to the way wind and lightening do].
