23 Also in those days I saw Jews who had married women from Ashdod, Ammon, and Moab. 24 Half the children couldn't even speak the language of Judah; all they knew was the language of Ashdod or some other tongue. 25 So I took those men to task, gave them a piece of my mind, even slapped some of them and jerked them by the hair. I made them swear to God: "Don't marry your daughters to their sons; and don't let their daughters marry your sons - and don't you yourselves marry them! 26 Didn't Solomon the king of Israel sin because of women just like these? Even though there was no king quite like him, and God loved him and made him king over all Israel, foreign women were his downfall. 27 Do you call this obedience - engaging in this extensive evil, showing yourselves faithless to God by marrying foreign wives?" 28 One of the sons of Joiada, the son of Eliashib the high priest, was a son-in-law of Sanballat the Horonite; I drove him out of my presence.

Matthew Henry's Commentary on Nehemiah 13:23-28

Commentary on Nehemiah 13:23-31

(Read Nehemiah 13:23-31)

If either parent be ungodly, corrupt nature will incline the children to take after that one; which is a strong reason why Christians should not be unequally yoked. In the education of children, great care should be taken about the government of their tongues; that they learn not the language of Ashdod, no impious or impure talk, no corrupt communication. Nehemiah showed the evil of these marriages. Some, more obstinate than the rest, he smote, that is, ordered them to be beaten by the officers according to the law, Deuteronomy 25:2,3. Here are Nehemiah's prayers on this occasion He prays, "Remember them, O my God." Lord, convince and convert them; put them in mind of what they should be and do. The best services to the public have been forgotten by those for whom they were done, therefore Nehemiah refers himself to God, to recompense him. This may well be the summary of our petitions; we need no more to make us happy than this; Remember me, O my God, for good. We may humbly hope that the Lord will remember us and our services, although, after lives of unwearied activity and usefulness, we shall still see cause to abhor ourselves and repent in dust and ashes, and to cry out with Nehemiah, Spare me, O my God, according to the greatness of they mercy.
