An explanation of the absence of all allusion in Haggai and Zechariah to the Return is certainly possible.

No one can fail to be struck with the spirituality of the teaching of Haggai and Zechariah. Their one ambition is to put courage from God into the poor hearts before them, that these out of their own resources may rebuild their Temple. As Zechariah puts it, _Not by might, nor by power, but by My Spirit, saith Jehovah of Hosts_.[584] It is obvious why men of this temper should refrain from appealing to the Return, or to the royal power of Persia by which it had been achieved. We can understand why, while the annals employed in the Book of Ezra record the appeal of the political leaders of the Jews to Darius upon the strength of the edict of Cyrus, the prophets, in their effort to encourage the people to make the most of what they themselves were and to enforce the omnipotence of God’s Spirit apart from all human aids, should be silent about the latter. We must also remember that Haggai and Zechariah were addressing a people to whom (whatever view we take of the transactions under Cyrus) the favour of Cyrus had been one vast disillusion in the light of the predictions of Second Isaiah.[585] The Persian magnate Sheshbazzar himself, invested with full power, had been unable to build the Temple for them, and had apparently disappeared from Judah, leaving his powers as Peḥah, or governor, to Zerubbabel. Was it not, then, as suitable to these circumstances, as it was essential to the prophets’ own religious temper, that Haggai and Zechariah should refrain from alluding to any of the political advantages, to which their countrymen had hitherto trusted in vain?[586]

Another fact should be marked. If Haggai is silent about any return from exile in the past, he is equally silent about any in the future. If for him no return had yet taken place, would he not have been likely to predict it as certain to happen?[587] At least his silence on the subject proves how absolutely he confined his thoughts to the circumstances before him, and to the needs of his people at the moment he addressed them. Kosters, indeed, alleges that Zechariah describes the Return from Exile as still future—viz. in the lyric piece appended to his Third Vision.[588] But, as we shall see when we come to it, this lyric piece is most probably an intrusion among the Visions, and is not to be assigned to Zechariah himself. Even, however, if it were from the same date and author as the Visions, it would not prove that no return from Babylon had taken place, but only that numbers of Jews still remained in Babylon.
