And of the angels he saith, Who maketh his angels spirits, and his ministers a flame of fire.
Ver. 7. A flame of fire] Hence they are called seraphims, because they flame, like heavenly salamanders, in the fire of pure and perfect love to God and his people; and cherubims, from their winged swiftness; swift they are as the wind; which may seem to be the sense of this text, compared withPsalms 104:4,5 .
