Nehemiah 13:23, 25-27

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

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