Then I beheld, and lo a likeness as the appearance of fire: from the appearance of his loins even downward, fire; and from his loins even upward, as the appearance of brightness, as the colour of amber.
A likeness - understand, 'of a man,' - i:e., of Messiah, the Angel of the Covenant, in the person of whom alone God manifests Himself (Ezekiel 1:26; John 1:18).
As the appearance of fire: from the appearance of his loins even downward, fire. The "fire" from "His loins downward," betokens the vengeance of God kindled against the wicked Jews, while searching and purifying the remnant to be spared.
From his loins even upward, as the appearance of brightness. The "brightness" upward betokens His unapproachable majesty (1 Timothy 6:16). For Hebrew х 'eesh (H784)], fire, the Septuagint, etc., read х 'iysh (H376)], a man.
As the colour of amber - as the glitter of chasmal (Fairbairn). (Note, Ezekiel 1:4, 'polished brass.')
