Deuteronomy 23:2-4

21st Century King James Version

² A bastard shall not enter into the congregation of the Lord; even to his tenth generation shall he not enter into the congregation of the Lord.

³ An Ammonite or Moabite shall not enter into the congregation of the Lord; even to their tenth generation shall they not enter into the congregation of the Lord for ever,

⁴ because they met you not with bread and with water in 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.
