نحميا ١٣:٢٨

Nehemiah acted with greater severity towards one of the sons of Joiada the high priest, and son-in-law of Sanballat. He drove him from him (מעלי, that he might not be a burden to me). The reason for this is not expressly stated, but is involved in the fact that he was son-in-law to Sanballat, i.e., had married a daughter of Sanballat the Horonite (Neh 2:10), who was so hostile to Nehemiah and to the Jewish community in general, and would not comply with the demand of Nehemiah that he should dismiss this wife. In this case, Nehemiah was obliged to interfere with authority. For this marriage was a pollution of the priesthood, and a breach of the covenant of the priesthood and the Levites. Hence he closes the narrative of this occurrence with the wish, Neh 13:29, that God would be mindful of them (להם, of those who had done such evil) on account of this pollution, etc., i.e., would punish or chastise them for it. גּאלי, stat. constr. pl. from גּאל, pollution (plurale tant.). It was a pollution of the priesthood to marry a heathen woman, such marriage being opposed to the sacredness of the priestly office, which a priest was to consider even in the choice of a wife, and because of which he might marry neither a whore, nor a feeble nor a divorced woman, while the high priest mighty marry only a virgin of his own people (Lev 21:7, Lev 21:14). The son of Joiada who had married a daughter of Sanballat was not indeed his presumptive successor (Johanan, Neh 12:11), for then he would have been spoken of by name, but a younger son, and therefore a simple priest; he was, however, so nearly related to the high priest, that by his marriage with a heathen woman the holiness of the high-priestly house was polluted, and therewith also "the covenant of the priesthood," i.e., not the coven…

Nehemiah, having finished what he undertook for the fencing and filling of the holy city, returned to the king his master, who was not willing to be long without him, as appears (Neh 13:6). But, after some time, he obtained leave to come back again to Jerusalem, to redress grievances, and purge out some corruptions which had crept in in his absence; and very active he was in reforming several abuses, which here we have an account of. I. He turned out from Israel the mixed multitude, the Moabites and Ammonites especially (Neh 13:1-3). With a particular indignation, he expelled Tobiah out of the lodgings he had got in the court of the temple (Neh 13:4-9). II. He secured the maintenance of the priests and Levites to them more firmly than it had been (Neh 13:10-14). III. He restrained the profanation of the sabbath day, and provided for the due sanctification of it (Neh 13:15-22). IV. He checked the growing mischief of marrying strange wives (Neh 13:23-31).

13:28 Even the family of the high priest, who were supposed to be Israel’s spiritual leaders, had participated in the sin of intermarriage with unbelieving foreigners (cp. Lev 21:14). Nehemiah banished the offender, stripping him of status and removing his rights in the Jewish community.
