Nehemiah 13:24-28

As for their children, half spoke in the language of Ashdod, and none of them knew how to speak the language of Judah, but only the language of his own people.

So I quarreled with them and cursed them, and struck some of them and pulled out their hair, and made them swear by God, “You shall not give your daughters to their sons, nor take any of their daughters for your sons or for yourselves.

Did Solomon the king of Israel not sin regarding these things? Yet among the many nations there was no king like him, and he was loved by his God, and God made him king over all Israel; yet the foreign women caused even him to sin.

Has it not then been reported about you that you have committed all this great evil by acting unfaithfully against our God, by marrying foreign women?”

Even one of the sons of Joiada, the son of Eliashib the high priest, became a son-in-law of Sanballat the Horonite, so I chased him away from me.
