Numbers 24:10-14

10Then Balak’s anger was kindled against Balaam, and he struck his hands together; and Balak said to Balaam, “I called you to curse my enemies, but behold, you have done nothing but bless them these three times.

11Therefore now flee to your place! I had intended to honor you greatly, but behold, the Lord has held you back from honor.”

12Balaam said to Balak, “Did I not tell your messengers whom you had sent to me,

13‘Even if Balak would give me his house full of silver and gold, I could not go beyond the command of the Lord, to do either good or bad of my own accord. What the Lord speaks, that I will speak?’

14And now, look, I am going to my people; come, I will advise you as to what this people [Israel] will do to your people [Moab] in the days to come.”
