Deuteronomy 23:3-8

3An Ammonite or Moabite shall not enter the assembly of the Lord; none of their descendants, even to the tenth generation, shall ever enter the assembly of the Lord,

4because they did not meet you with bread (food) and water on the road as you came out of Egypt, and because they hired [to act] against you Balaam the son of Beor from Pethor of Mesopotamia, to curse you.

5Nevertheless, the Lord your God was not willing to listen to Balaam, but the Lord your God turned the curse into a blessing for you because the Lord your God has loved you.

6You shall never seek their peace nor their prosperity all your days.

7“You shall not detest an Edomite, for he is your brother [Esau’s descendant]. You shall not detest an Egyptian, because you were a stranger (resident alien, foreigner) in his land.

8Their children of the third generation who are born to them may enter the assembly of the Lord.
