Deuteronomy 23:3, 4
No Ammonite or Moabite or any of their descendants may enter the assembly of the LORD, even to the tenth generation. / For they did not meet you with food and water on your way out of Egypt, and they hired Balaam son of Beor from Pethor in Aram-naharaim to curse you.
Nehemiah 13:1, 2
At that time the Book of Moses was read aloud in the hearing of the people, and in it they found the passage stating that no Ammonite or Moabite should ever enter the assembly of God, / because they had not met the Israelites with food and water, but had hired Balaam to call down a curse against them (although our God had turned the curse into a blessing).
