Nehemiah 13:1-3

1 In that day they read in the book of Moses in the ears of the people; and it was found written in it, that the Ammonites and Moabites should not enter into the congregation of God for ever;
2 because they met not the children of Israel with bread and water, but hired Balaam against them to curse them: but our God turned the curse into a blessing.
3 And it came to pass, when they heard the law, that they were separated, every alien in Israel.
