The Visions in which Zechariah treats of the outer history of the world are the first two and the last, and in these we notice the influence of the Apocalypse developed during the Exile. In Zechariah’s day Israel had no stage for their history save the site of Jerusalem and its immediate neighbourhood. So long as he keeps to this Zechariah is as practical and matter-of-fact as any of the prophets, but when he has to go beyond it to describe the general overthrow of the heathen, he is unable to project that, as Amos or Isaiah did, in terms of historic battle, and has to call in the apocalyptic. A people such as that poor colony of exiles, with no issue upon history, is forced to take refuge in Apocalypse, and carries with it even those of its prophets whose conscience, like Zechariah’s, is most strongly bent upon the practical present. Consequently these three historical Visions are the most vague of the eight. They reveal the whole earth under the care of Jehovah and the patrol of His angels. They definitely predict the overthrow of the heathen empires. But, unlike Amos or Isaiah, the prophet does not see by what political movements this is to be effected. The world _is_ still _quiet and at peace_.[792] The time is hidden in the Divine counsels; the means, though clearly symbolised in _four smiths_ who come forward to smite the horns of the heathen,[793] and in a chariot which carries God’s wrath to the North,[794] are obscure. The prophet appears to have intended, not any definite individuals or political movements of the immediate future, but God’s own supernatural forces. In other words, the Smiths and Chariots are not an allegory of history, but powers apocalyptic. The forms of the symbols were derived by Zechariah from different sources. Perhaps that of the _smiths_ who destroy the horns in the Second Vision was suggested by the _smiths of destruction_ threatened upon Ammon by Ezekiel.[795] In the horsemen of the First Vision and the chariots of the Eighth, Ewald sees a reflection of the couriers and posts which Darius organised throughout the empire; they are more probably, as we shall see, a reflection of the military bands and patrols of the Persians. But from whatever quarter Zechariah derived the exact aspect of these Divine messengers, he found many precedents for them in the native beliefs of Israel. They are, in short, angels, incarnate as Hebrew angels always were, and in fashion like men. But this brings up the whole subject of the angels, whom he also sees employed as the mediators of God’s Word to him; and that is large enough to be left to a chapter by itself.[796] We have now before us all the influences which led Zechariah to the main form and chief features of his Visions. 3.
