Strictly as this separation was carried out, this evil was not thereby done away with for ever, nor even for very long. After the arrival of Nehemiah at Jerusalem, when the building of the wall was concluded, the congregation again bound themselves by an oath, on the occasion of a day of prayer and fasting, to contract no more such illegal marriages (Neh 10:31). Nevertheless, Nehemiah, on his second return to Jerusalem, some five and twenty to thirty years after the dissolution of these marriages by Ezra, again found Jews who had married women of Ashdod, Moab, and Ammon, and children of these marriages who spoke the tongue of Ashdod, and could not speak the Jews' language, and even one of the sons of the high priest Jehoiada allied to a daughter of Sanballat the Horonite (Neh 13:28, etc.). Such a phenomenon, however strange it may appear on a superficial view of the matter, becomes comprehensible when we consider more closely the circumstances of the times. The nucleus of the Israelite community in Jerusalem and Judah was formed by those exiles who returned from Babylon with Zerubbabel and Ezra; and to this nucleus the remnant of Jewish and Israelite descent which had been left in the land was gradually united, after the rebuilding of the temple and the restoration of the worship of Jahve. Those who returned from Babylon, as well as those who remained in the land, had now, however, lived seventy, and some of them one hundred and fifty, years (from the captivity of Jehoiachin in 599, to the return of Ezra in 457) among the heathen, and in the midst of heathen surroundings, and had thus become so accustomed to intercourse with them in civil and social transactions, that the consciousness of the barriers placed by the Mosaic law between Israel, the people of Jahve, and the Gentiles, was more and more obliterated. And this would specially be the case when the Gentiles who entered into matrimonial alliance with Israelites did not flagrantly practise idolatrous worship, i.e., did not offer sacrifice to heathen deities. Under such circumstances, it must have been extremely difficult to do away entirely with these unlawful unions; although, without a thorough reform in this respect, the successful development of the new community in the land of their fathers was not to be obtained.
Ezra's narrative of his agency in Jerusalem closes with the account of the dissolution of the unlawful marriages then existing. What he subsequently effected for the revival of religion and morality in the re-established community, in conformity with the law of God, was more of an inward and spiritual kind; and was either of such a nature that no striking results ensued, which could furnish matter for historical narrative, or was performed during the period of his joint agency with Nehemiah, of which an account is furnished by the latter in the record he has handed down to us (Neh 8:10).
