Conceptions of God
Ezekiel’s conception of Jehovah appears in the” visions of God” which he describes (chaps. 1; 8; 10; 43.). These visions were all alike, and they reveal his general impression of that which Jehovah is: the fourfold nature of the cherubim, of their faces and wings and of the wheels, all forming a chariot moving in every direction alike, and with the velocity suggested by the wings and wheels, symbolises the omnipresence of Jehovah, while the eyes of which the whole are full are a token of His omniscience. The throne above the firmament on which He sat indicates that He is King in heaven, God over all, omnipotence. The Divine Being Himself appeared as of human form, while His nature was light, of such brightness that fire fitly represented Him only from the loins downwards; from the loins upwards the effulgence was something purer and more dazzling, and He was surrounded by a brightness like that of the rainbow in the day of ram. This glory, which contains Himself within it (Ezekiel 10:4,18; Ezekiel 43:5; Ezekiel 34:6), is that which is manifested to men. (A. B. Davidson, D. D.)
Man a type of the supernatural
All the analogies of human thought are in themselves analogies of nature; and in proportion as they are built up or are perceived by mind in its higher attributes and work, they are part and parcel of natural truth. Man--he whom the Greeks call Anthropos, because, as it has been supposed, he is the only being whose look is upward--man is a part of nature, and no artificial definitions can separate him from it. And yet in another sense it is true that man is above nature--outside of it; and in this aspect he is the very type and image of the “supernatural.” (Duke of Argyll.)

The significance of the rainbow
Ezekiel was reminded that he had to present God before the people as clothed with fire--a symbol, probably, of His coming indignation on the last of Jerusalem’s inhabitants. But, not to disturb the righteous, or to give them the least idea for supposing that, in the final desolation of Jerusalem, God’s covenant should cease, the vision went on (verse 28) to reveal a rainbow overarching this fiery throne, the mild lustre of which outshone its blazing glare. Could anything be more gracious? From that time, both the prophet and His faithful people might well rest assured that they were safe. God would not, and could not, forsake them. The bow of the covenant was above them, far beyond the reach of those changing providences which were represented as going forward so rapidly and incessantly below them. And even thus, amidst the changes and troubles of this mortal life, the true Israel, the believers in Christ, are safe under God’s covenant mercy and grace. (J. H. Titcomb.)
