Nehemiah 13:23-28

23Also at that time, I discovered that men from Judah had married foreign women. They were women who came from Ashdod, Ammon and Moab.

24Half of their children spoke the language of Ashdod, or a language of the other foreign nations. They did not know how to speak the language of Judah.

25I was angry with them. I asked God to curse them. I hit some of the men. I pulled out the hair of some of them. I told them to make a promise in God's name. I said to them, ‘You must not let your daughters marry the sons of those foreign people. You must not let their daughters marry your sons. You yourselves must not marry foreign women either.

26Solomon, king of Israel, did a bad thing when he married foreign women. There was no other king as great as him in any other nation. God loved him. God chose him to be king over all Israel. But Solomon's foreign wives caused him to do bad things, even though he was so great.

27We can never agree to all the evil things that you have done. If we all married foreign women, we would not be faithful to our God.’

28Joiada was the son of Eliashib, the leader of the priests. One of Joiada's sons had married a daughter of Sanballat, who came from Horon. I sent Joiada's son away from Jerusalem.
