Ezekiel 1:27

And I saw as the colour of amber
That is, the man upon the throne looked like the colour of amber; of which (See Gill on Ezekiel 1:4); as the appearance of fire round about within it;
which may denote the deity of Christ, or Christ as God, who is a consuming fire to his enemies; a fire enlightening and warming to his people; as a wall of fire protecting them; and as a pillar of fire guiding and directing them, as he did the Israelites in the wilderness; and who has such light and glory in him, as is incomprehensible to us; and therefore this fire appeared round about within, the colour of amber, and under his human nature, through which it broke forth: from the appearance of his loins even upward, and from the appearance
of his loins even downward, I saw as it were the appearance of fire;
it reached upwards and downwards, as well as all around him: and it had brightness round about;
the fire; which shone through the human nature, and was upon it, in virtue of its union to the Son of God; and through the Gospel, in which, as in a glass, the glory of the Lord is seen; and which will be brighter and brighter in the latter day; which may be signified by the appearance of his loins downward.
