Deuteronomy 23:3-5

Living Bible

³ “No Ammonite or Moabite may ever enter the sanctuary, even after the tenth generation. ⁴ The reason for this law is that these nations did not welcome you with food and water when you came out of Egypt; they even tried to hire Balaam, the son of Beor from Pethor, Mesopotamia, to curse you. ⁵ But the Lord wouldn’t listen to Balaam; instead, he turned the intended curse into a blessing for you because the Lord loves you.
