Nehemiah 13:26-27

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.’
