Numbers 24:10-14

10Then Balak became furious with Balaam, struck his hands together, and said to him, “I summoned you to put a curse on my enemies, but instead, you have blessed them these three times.

11Now go to your home! I said I would reward you richly, but look, the Lord has denied you a reward.”

12Balaam answered Balak, “Didn’t I previously tell the messengers you sent me:

13If Balak were to give me his house full of silver and gold, I could not go against the Lord’s command, to do anything good or bad of my own will? I will say whatever the Lord says.

14Now I am going back to my people, but first, let me warn you what these people will do to your people in the future.”
