The explanation of this change that has come over prophecy must be sought for in certain habits which the people formed in exile. During the Exile several causes conspired to develop among Hebrew writers the tempers both of symbolism and apocalypse. The chief of these was their separation from the realities of civic life, with the opportunity their political leisure afforded them of brooding and dreaming. Facts and Divine promises, which had previously to be dealt with by the conscience of the moment, were left to be worked out by the imagination. The exiles were not responsible citizens or statesmen, but dreamers. They were inspired by mighty hopes for the future, and not fettered by the practical necessities of a definite historical situation upon which these hopes had to be immediately realised. They had a far-off horizon to build upon, and they occupied the whole breadth of it. They had a long time to build, and they elaborated the minutest details of their architecture. Consequently their construction of the future of Israel, and their description of the processes by which it was to be reached, became colossal, ornate and lavishly symbolic. Nor could the exiles fail to receive stimulus for all this from the rich imagery of Babylonian art by which they were surrounded. Under these influences there were three strong developments in Israel. One was that development of Apocalypse the first beginnings of which we traced in Zephaniah—the representation of God’s providence of the world and of His people, not by the ordinary political and military processes of history, but by awful convulsions and catastrophes, both in nature and in politics, in which God Himself appeared, either alone in sudden glory or by the mediation of heavenly armies. The second—and it was but a part of the first—was the development of a belief in Angels: superhuman beings who had not only a part to play in the apocalyptic wars and revolutions; but, in the growing sense, which characterises the period, of God’s distance and awfulness, were believed to act as His agents in the communication of His Word to men. And, thirdly, there was the development of the Ritual. To some minds this may appear the strangest of all the effects of the Exile. The fall of the Temple, its hierarchy and sacrifices, might be supposed to enforce more spiritual conceptions of God and of His communion with His people. And no doubt it did. The impossibility of the legal sacrifices in exile opened the mind of Israel to the belief that God was satisfied with the sacrifices of the broken heart, and drew near, without mediation, to all who were humble and pure of heart. But no one in Israel therefore understood that these sacrifices were for ever abolished. Their interruption was regarded as merely temporary even by the most spiritual of Jewish writers. The Fifty-First Psalm, for instance, which declares that _the sacrifices of God are a broken spirit; a broken and a contrite heart, O
