Numbers 23:5, 8, 11

The LORD gave Balaam a message for King Balak. Then he said, “Go back to Balak and give him my message.”

But how can I curse those whom God has not cursed? How can I condemn those whom the LORD has not condemned?

Then King Balak demanded of Balaam, “What have you done to me? I brought you to curse my enemies. Instead, you have blessed them!”
