Numbers 22:36-40

36When Balak heard that Balaam had come, he went out to meet him at the city of Moab, on the border formed by the Arnon, at the extremity of the border.

37And Balak said to Balaam, "Did I not send to you to call you? Why did you not come to me? Am I not able to honor you?"

38Balaam said to Balak, "Behold, I have come to you! Have I now any power of my own to speak anything? The word that God puts in my mouth, that must I speak."

39Then Balaam went with Balak, and they came to Kiriath-huzoth.

40And Balak sacrificed oxen and sheep, and sent for Balaam and for the princes who were with him.
