Deuteronomy 23:2-4

International Children’s Bible

² No one born to parents who were forbidden by law to marry may come into the meeting to worship the Lord. His descendants for ten generations may not come in either.

³ No Ammonite or Moabite may come into the meeting to worship the Lord. And none of their descendants for ten generations may come in. ⁴ This is because the Ammonites and Moabites did not give you bread and water when you came out of Egypt. And they hired Balaam to put a curse on you. He was the son of Beor from Pethor in Northwest Mesopotamia.
