Joshua 24:9-10 When Balak son of Zippor, the king of Moab, prepared to fight against Israel, he sent for Balaam son of Beor to put a curse on you. But I would not listen to Balaam, so he blessed you again and again, and I delivered you out of his hand.
Nehemiah 13:1-2 On that day the Book of Moses was read aloud in the hearing of the people and there it was found written that no Ammonite or Moabite should ever be admitted into the assembly of God, because they had not met the Israelites with food and water but had hired Balaam to call a curse down on them. (Our God, however, turned the curse into a blessing.)
Micah 6:5 My people, remember what Balak king of Moab counseled and what Balaam son of Beor answered. Remember your journey from Shittim to Gilgal, that you may know the righteous acts of the LORD.
