Deuteronomy 23:2-9

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

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.

6Thou shalt not seek their peace nor their prosperity all thy days for ever.

7Thou shalt not abhor an Edomite; for he is thy brother. Thou shalt not abhor an Egyptian; because thou wast a sojourner in his land.

8Children that are born to them shall come into the congregation of Jehovah in the third generation.

9When thou goest forth into camp against thine enemies, then keep thee from every evil thing.
