Deuteronomy 23:2-4

Darby Translation

² A bastard shall not come into the congregation of Jehovah; even his tenth generation shall not come into the congregation of Jehovah.

³ An 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;

⁴ because 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.
