Nehemiah 13:23-28

23About the same time I realized that some of the men of Judah had married women from Ashdod, Ammon, and Moab.

24Furthermore, half their children spoke the language of Ashdod or of some other people and could not speak the language of Judah at all.

25So I confronted them and called down curses on them. I beat some of them and pulled out their hair. I made them swear in the name of God that they would not let their children intermarry with the pagan people of the land.

26“Wasn’t this exactly what led King Solomon of Israel into sin?” I demanded. “There was no king from any nation who could compare to him, and God loved him and made him king over all Israel. But even he was led into sin by his foreign wives.

27How could you even think of committing this sinful deed and acting unfaithfully toward God by marrying foreign women?”

28One of the sons of Joiada son of Eliashib the high priest had married a daughter of Sanballat the Horonite, so I banished him from my presence.
