In spite of their obvious dissimilarities the two visions have enough in common to show that Ezekiel's thoughts concerning God had been largely influenced by the study of Isaiah. Truths that had perhaps long been latent in his mind now emerge into clear consciousness, clothed in forms which bear the impress of the mind in which they were first conceived. The fundamental idea is the same in each vision: the absolute and universal sovereignty of God. “Mine eyes have seen the King, Jehovah of hosts.” Jehovah appears in human form, seated on a throne and attended by ministering creatures which serve to show forth some part of His glory. In the one case they are seraphim, in the other cherubim; and the functions imposed on them by the structure of the vision are very diverse in the two cases. But the points in which they agree are more significant than those in which they differ. They are the agents through whom Jehovah exercises His sovereign authority, beings full of life and intelligence and moving in swift response to His will. Although free from earthly imperfection they cover themselves with their wings before His majesty, in token of the reverence which is due from the creature in presence of the Creator. For the rest they are symbolic figures embodying in themselves certain attributes of the Deity, or certain aspects of His kingship. Nor can Ezekiel any more than Isaiah think of Jehovah as the King apart from the emblems associated with the worship of His earthly sanctuary. The cherubim themselves are borrowed from the imagery of the Temple, although their forms are different from those which stood in the Holy of holies. So again the altar, which was naturally suggested to Isaiah by the scene of his vision being laid in the Temple, appears in Ezekiel's vision in the form of the hearth of [pg 034] glowing coals which is under the divine throne. It is true that the fire symbolises destructive might rather than purifying energy (see ch. x. 2), but it can hardly be doubted that the origin of the symbol is the altar-hearth of the sanctuary and of Isaiah's vision. It is as if the essence of the Temple and its worship were transferred to the sphere of heavenly realities where Jehovah's glory is fully manifested. All this, therefore, is nothing more than the embodiment of the fundamental truth of the Old Testament religion—that Jehovah is the almighty King of heaven and earth, that He executes His sovereign purposes with irresistible power, and that it is the highest privilege of men on earth to render to Him the homage and adoration which the sight of His glory draws forth from heavenly beings.
The idea of Jehovah's kingship, however, is presented in the Old Testament under two aspects. On the one hand, it denotes the moral sovereignty of God over the people whom He had chosen as His own and to whom His will was continuously revealed as the guide of their national and social life. On the other hand, it denotes God's absolute dominion over the forces of nature and the events of history, in virtue of which all things are the unconscious instruments of His purposes. These two truths can never be separated, although the emphasis is laid sometimes on the one and sometimes on the other. Thus in Isaiah's vision the emphasis lies perhaps more on the doctrine of Jehovah's kingship over Israel. It is true that He is at the same time represented as One whose glory is the “fulness of the whole earth,” and who therefore manifests His power and presence in every part of His world-wide dominions. But the fact that Jehovah's palace is the idealised Temple of Jerusalem suggests at once, what all the teaching of the prophet confirms, that the nation of Israel is the special sphere within which His kingly [pg 035] authority is to obtain practical recognition. While no man had a firmer grasp of the truth that God wields all natural forces and overrules the actions of men in carrying out His providential designs, yet the leading ideas of His ministry are those which spring from the thought of Jehovah's presence in the midst of His people and the obligation that lies on Israel to recognise His sovereignty. He is, to use Isaiah's own expression, the “Holy One of Israel.”
This aspect of the divine kingship is undoubtedly represented in the vision of Ezekiel. We have remarked that the imagery of the vision is to some extent moulded on the idea of the sanctuary as the seat of Jehovah's government, and we shall find later on that the final resting-place of this emblem of His presence is a restored sanctuary in the land of Canaan. But the circumstances under which Ezekiel was called to be a prophet required that prominence should be given to the complementary truth that the kingship of Jehovah was independent of His special relation to Israel. For the present the tie between Jehovah and His land was dissolved. Israel had disowned her divine King, and was left to suffer the consequences of her disloyalty. Hence it is that the vision appears, not from the direction of Jerusalem, but “out of the north,” in token that God has departed from His Temple and abandoned it to its enemies. In this way the vision granted to the exiled prophet on the plain of Babylonia embodied a truth opposed to the religious prejudices of his time, but reassuring to himself—that the fall of Israel leaves the essential sovereignty of Jehovah untouched; that He still lives and reigns, although His people are trodden underfoot by worshippers of other gods. But more than this, we can see that on the whole the tendency of Ezekiel's vision, as distinguished from that of Isaiah, is to emphasise the universality of Jehovah's [pg 036] relations to the world of nature and of mankind. His throne rests here on a sapphire stone, the symbol of heavenly purity, to signify that His true dwelling-place is above the firmament, in the heavens, which are equally near to every region of the earth. Moreover, it is mounted on a chariot, by which it is moved from place to place with a velocity which suggests ubiquity, and the chariot is borne by “living creatures” whose forms unite all that is symbolical of power and dignity in the living world. Further, the shape of the chariot, which is foursquare, and the disposition of the wheels and cherubim, which is such that there is no before or behind, but the same front presented to each of the four quarters of the globe, indicate that all parts of the universe are alike accessible to the presence of God. Finally, the wheels and the cherubim are covered with eyes, to denote that all things are open to the view of Him who sits on the throne. The attributes of God here symbolised are those which express His relations to created existence as a whole—omnipresence, omnipotence, omniscience. These ideas are obviously incapable of adequate representation by any sensuous image—they can only be suggested to the mind; and it is just the effort to suggest such transcendental attributes that imparts to the vision the character of obscurity which attaches to so many of its details.
Another point of comparison between Isaiah and Ezekiel is suggested by the name which the latter constantly uses for the appearance which he sees, or rather perhaps for that part of it which represents the personal appearance of God. He calls it the “glory of Jehovah,” or “glory of the God of Israel.” The word for glory (kābôd) is used in a variety of senses in the Old Testament. Etymologically it comes from a root expressing the idea of heaviness. When used, as here, concretely, it signifies that which is the outward manifestation of power or [pg 037] worth or dignity. In human affairs it may be used of a man's wealth, or the pomp and circumstance of military array, or the splendour and pageantry of a royal court, those things which oppress the minds of common men with a sense of magnificence. In like manner, when applied to God, it denotes some reflection in the outer world of His majesty, something that at once reveals and conceals His essential Godhead. Now we remember that the second line of the seraphs' hymn conveyed to Isaiah's mind this thought, that “that which fills the whole earth is His glory.” What is this “filling of the whole earth” in which the prophet sees the effulgence of the divine glory? Is his feeling akin to Wordsworth's
“sense sublime
Of something far more deeply interfused,
Whose dwelling is the light of setting suns,
And the round ocean, and the living air,
And the blue sky, and in the mind of man”?
At least the words must surely mean that all through nature Isaiah recognised that which declares the glory of God, and therefore in some sense reveals Him. Although they do not teach a doctrine of the divine immanence, they contain all that is religiously valuable in that doctrine. In Ezekiel, however, we find nothing that looks in this direction. It is characteristic of his thoughts about God that the very word “glory” which Isaiah uses of something diffused through the earth is here employed to express the concentration of all divine qualities in a single image of dazzling splendour, but belonging to heaven rather than to earth. Glory is here equivalent to brightness, as in the ancient conception of the bright cloud which led the people through the desert and that which filled the Temple with overpowering light when Jehovah took possession of it (2 Chron. vii. 1-3). In a striking passage of his last [pg 038] vision Ezekiel describes how this scene will be repeated when Jehovah returns to take up His abode amongst His people and the earth will be lighted up with His glory (ch. xliii. 2). But meanwhile it may seem to us that earth is left poorer by the loss of that aspect of nature in which Isaiah discovered a revelation of the divine.
