Nehemiah 13:23-29

23In those days I also saw Jews who had married women of Ashdod, Ammon, and Moab.

24And half of their children spoke the language of Ashdod, and could not speak the language of Judah, but spoke according to the language of one or the other people.

25So I contended with them and cursed them, struck some of them and pulled out their hair, and made them swear by God, saying, “You shall not give your daughters as wives to their sons, nor take their daughters for your sons or yourselves.

26Did not Solomon king of Israel sin by these things? Yet among many nations there was no king like him, who was beloved of his God; and God made him king over all Israel. Nevertheless pagan women caused even him to sin.

27Should we then hear of your doing all this great evil, transgressing against our God by marrying pagan women?”

28And one of the sons of Joiada, the son of Eliashib the high priest, was a son-in-law of Sanballat the Horonite; therefore I drove him from me.

29Remember them, O my God, because they have defiled the priesthood and the covenant of the priesthood and the Levites.
