Deuteronomy 23:1-4

1“If a man’s testicles are crushed or his penis is cut off, he may not be admitted to the assembly of the Lord.

2“If a person is illegitimate by birth, neither he nor his descendants for ten generations may be admitted to the assembly of the Lord.

3“No Ammonite or Moabite or any of their descendants for ten generations may be admitted to the assembly of the Lord.

4These nations did not welcome you with food and water when you came out of Egypt. Instead, they hired Balaam son of Beor from Pethor in distant Aram-naharaim to curse you.
