Deuteronomy 23:2-4

Modern English Version

² No one of illegitimate birth may enter the assembly of the Lord. Even to his tenth generation no one related to him may enter the assembly of the Lord.

³ No Ammonite or Moabite may enter the assembly of the Lord. Even to their tenth generation they may not enter the assembly of the Lord forever, ⁴ because they refused you bread and water on the way, when you came from out of Egypt and because they hired Balaam, the son of Beor of Pethor of Mesopotamia, against you to curse you.
