Numbers 22:36-40

36Now when Balak heard that Balaam was coming, he went out to meet him at the city of Moab, which is on the border at the Arnon, the boundary of the territory.

37Then Balak said to Balaam, “Did I not earnestly send to you, calling for you? Why did you not come to me? Am I not able to honor you?”

38And Balaam said to Balak, “Look, I have come to you! Now, have I any power at all to say anything? The word that God puts in my mouth, that I must speak.”

39So Balaam went with Balak, and they came to Kirjath Huzoth.

40Then Balak offered oxen and sheep, and he sent some to Balaam and to the princes who were with him.
