Now, as in the previous cases of Cyrus and Darius, we are confronted with the question, How came the Persian king to issue such a decree? It has been suggested that as Egypt was in revolt at the time, he desired to strengthen the friendly colony at Jerusalem as a western bulwark. But, as we have seen in the case of Cyrus, the Jews were too few and feeble to be taken much account of among the gigantic forces of the vast empire; and, moreover, it was not the military fortification of Jerusalem--certainly a valuable stronghold when well maintained--but the religious services of the temple and the observance of The Law that this edict aimed at aiding and encouraging. No doubt in times of unsettlement the king would behave most favourably towards a loyal section of his people. Still, more must be assigned as an adequate motive for his action. Ezra is charged as a special commissioner to investigate the condition of the Jews in Palestine. He is to "inquire concerning Judah and Jerusalem."[82] Inasmuch as it was customary for the Persian monarchs to send out inspectors from time to time to examine and report on the condition of the more remote districts of their extensive empire, it has been plausibly suggested that Ezra may have been similarly employed. But in the chronicler's report of the edict we read, immediately after the injunction to make the investigation, an important addition describing how this was to be done, viz., "According to the law of thy God which is in thine hand,"[83] which shows that Ezra's inquiry was to be of a religious character, and as a preliminary to the exaction of obedience to the Jewish law. It may be said that this clause was not a part of the original decree; but the drift of the edict is religious throughout rather than political, and therefore the clause in question is fully in harmony with its character. There is one sentence which is of the deepest significance, if only we can believe that it embodies an original utterance of the king himself--"Whatsoever is commanded by the God of heaven, let it be done exactly for the house of the God of heaven; _for why should there be wrath against the realm of the king and his sons_?"[84] While his empire was threatened by dangerous revolts, Artaxerxes seems to have desired to conciliate the God whom the most devout of his people regarded with supreme awe.
