Ezekiel 1:27

In fact, even in Ezekiel, from what looked like from his waist upward God resembled amber, but from his waist downward he resembled fire. Whatever is above is gold, and whatever is below is ready for purgation in Gehenna.

(Verse 27, 28.) And I saw something like the appearance of electrum, like the appearance of fire within it all around. From the appearance of his loins and upward, I saw something like the appearance of glowing fire all around, like the appearance of a rainbow in the clouds on a rainy day. This was the appearance of the splendor of the Lord's glory. When I saw it, I fell facedown and heard a voice speaking. The electrum had the appearance of fire both inside and outside.

"And I saw something like the appearance of amber." And so that the holy prophet might show that he had seen the union of both natures in His person, he immediately added: "And I saw something like the appearance of amber." What is it that the appearance of a man is seen upon the throne as the likeness of amber, except that in amber, as we said far above, gold and silver are mixed, so that one thing is made from two metals? In which both the brightness of the gold is tempered through the silver, and through the brightness of the gold the appearance of the silver is made bright. But in our Redeemer both natures, that is of divinity and humanity, are united and joined to each other without confusion and inseparably, so that through his humanity the brightness of his divinity could be tempered to our eyes, and through his divinity the human nature in him would be made bright, and being exalted would have splendor beyond what it had been created with.

"As the appearance of fire within all around, from his loins and upward; and from his loins downward I saw as it were the appearance of shining fire round about." What is it that the Mediator of God and men, the man Christ Jesus, is described as having the appearance of fire inwardly round about from the loins and upward, and from the loins and downward the appearance of shining fire round about? For we must investigate why from the loins and upward He is said to have fire inwardly, yet not shining fire; but from the loins and downward He is said to have the appearance of fire, yet it is not mentioned that He has it inwardly, because He is described as having it both shining and round about. For what is expressed by the name of loins, if not the propagation of mortality? On account of which it is also said of Levi that he was still in the loins of his father when Melchizedek met Abraham. From the loins of Abraham indeed the Virgin Mary came forth, in whose womb the Only-begotten of the Father deigned to become incarnate through the Holy Spirit. From which incarnation God became known to the whole world, as it is said through the Psalmist: Gird your sword upon your thigh, O most mighty one. For the Most Mighty took His sword upon His thigh, because the word of His preaching gained strength from His incarnation. But what does this fire signify, if not the ardor of the Holy Spirit, who sets ablaze the hearts that He has filled? Of which the Truth Himself says: I came to cast fire upon the earth. […]

Amber - In this colour does Christ appear against the rebellious Jews; he that would have visited them clothed with the garments of salvation, now puts on the garments of vengeance, expressed by such metaphors. Brightness - Majesty, justice, and unstained holiness, shine round about him.
