Numbers 24:10-13

10Then Balak’s anger burned against Balaam, and he struck his hands together and said to Balaam, “I summoned you to curse my enemies, but behold, you have persisted in blessing them these three times. 11Therefore, flee at once to your home! I said I would reward you richly, but instead the LORD has denied your reward.”

12Balaam answered Balak, “Did I not already tell the messengers you sent me 13that even if Balak were to give me his house full of silver and gold, I could not do anything of my own accord, good or bad, to go beyond the command of the LORD? I must speak whatever the LORD says.
