Deuteronomy 23:2-9

2No one of illegitimate birth shall enter the assembly of the Lord; none of his descendants, even to the tenth generation, shall enter the assembly of the Lord. 31No Ammonite or Moabite shall enter the assembly of the Lord; none of their descendants, even to the tenth generation, shall ever enter the assembly of the Lord, 42because they did not meet you with 3food and water on the way when you came out of Egypt, and because they hired against you 4Balaam the son of Beor from Pethor of 5Mesopotamia, to curse you. 5Nevertheless, the Lord your God was not willing to listen to Balaam, but the Lord your God 6turned the curse into a blessing for you because the Lord your God 7loves you. 68You shall never seek their peace or their prosperity all your days.

7“You shall not detest an Edomite, for 9he is your brother; you shall not detest an Egyptian, 10because you were an alien in his land. 8The sons of the third generation who are born to them may enter the assembly of the Lord.

9“When you go out as 11an army against your enemies, you shall keep yourself from every evil thing.
