Deuteronomy 23:3-5

3An Ammonite or Moabite shall not come into the congregation of Jehovah; even their tenth generation shall not come into the congregation of Jehovah for ever;

4because they met you not with bread and with water on the way, when ye came forth out of Egypt, and because they hired against thee Balaam the son of Beor, of Pethor of Mesopotamia, to curse thee.

5But Jehovah thy 1God would not listen to Balaam; and Jehovah thy 2God turned the curse into blessing unto thee, because Jehovah thy 3God loved thee.
