Deuteronomy 23:3-4

Revised Standard Version

³ “No Ammonite or Moabite shall enter the assembly of the Lord; even to the tenth generation none belonging to them shall enter the assembly of the Lord for ever; ⁴ because they did not meet you with bread and with water on the way, when you came forth out of Egypt, and because they hired against you Balaam the son of Be′or from Pethor of Mesopota′mia, to curse you.
