Thematic Bible: Ammonites and moabites

An Ammonite or Moabite shall not enter into the congregation of the Lord; even to their tenth generation their descendants shall not enter into the assembly of the Lord forever, Because they did not meet you with food and water on the way when you came forth out of Egypt, and because they hired Balaam son of Beor of Pethor of Mesopotamia against you to curse you. Nevertheless, the Lord your God would not listen to Balaam, but the Lord your God turned the curse into a blessing to you, because the Lord your God loves you. read more.
You shall not seek their peace or their prosperity all your days forever.
