Nehemiah 13:24

21 but I warned them, “Why are you camping in front of the wall? If you do it again, I will lay hands on you.” From that time on, they did not return on the Sabbath.

22 Then I instructed the Levites to purify themselves and guard the gates in order to keep the Sabbath day holy. Remember me for this as well, O my God, and show me mercy according to Your abundant loving devotion.

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

24 Half of their children spoke the language of Ashdod or of the other peoples, but could not speak the language of Judah.

25 I rebuked them and called down curses on them. I beat some of these men and pulled out their hair. Then I made them take an oath before God and said, “You must not give your daughters in marriage to their sons or take their daughters as wives for your sons or for yourselves!

26 Did not King Solomon of Israel sin in matters like this? There was not a king like him among many nations, and he was loved by his God, who made him king over all Israel—yet foreign women drew him into sin.

27 Must we now hear that you too are doing all this terrible evil and acting unfaithfully against our God by marrying foreign women?”
