Numbers 24:10-14

10Then Balak’s anger burned against Balaam. He struck his hands together and said to him, “I summoned you to curse my enemies, but you have blessed them these three times.

11Now leave at once and go home! I said I would reward you handsomely, but the LORD has kept you from being rewarded.” 12Balaam answered Balak, “Did I not tell the messengers you sent me, 13‘Even if Balak gave me all the silver and gold in his palace, I could not do anything of my own accord, good or bad, to go beyond the command of the LORD —and I must say only what the LORD says’?

14Now I am going back to my people, but come, let me warn you of what this people will do to your people in days to come.”
