Nehemiah 13:23-27

In those days I saw men of Judah who had married women from Ashdod, Ammon, and Moab. Half their children were speaking the language of Ashdod or some other place, and they couldn’t speak the language of Judah. I argued with those people, put curses on them, hit some of them, and pulled out their hair. I forced them to make a promise to God, saying, “Do not let your daughters marry the sons of foreigners, and do not take the daughters of foreigners as wives for your sons or yourselves. Foreign women made King Solomon of Israel sin. There was never a king like him in any of the nations. God loved Solomon and made him king over all Israel, but foreign women made him sin. And now you are not obedient when you do this evil thing. You are unfaithful to our God when you marry foreign wives.”
