Nehemiah 13:23-25 CSB
In those days I also saw Jews who had married women from Ashdod, Ammon, and Moab. Half of their children spoke the language of Ashdod or the language of one of the other peoples but could not speak Hebrew. I rebuked them, cursed them, beat some of their men, and pulled out their hair. I forced them to 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 yourselves!
