Nehemiah 13:1-2
Nehemiah 13: 1 to 2
1 On that day they read the Book of Mosesto the people, and they found that it said no Ammonite or Moabite should ever be allowed in the meeting to worship.
2 The Ammonites and Moabites had not welcomed the Israelites with food and water. Instead, they had hired Balaam to put a curse on Israel. (But our God turned the curse into a blessing.)
