Deuteronomy 23:5-10

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.

9“When you go out as an army [to fight] against your enemies, you shall keep yourselves from every evil [thing].

10“If there is any man among you who is [ceremonially] unclean because of nocturnal emission, then he must go outside the camp; he shall not come back to the camp.
