Malice: Ammonites Toward the Israelites
Source: Nav
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.
