Numbers 22:36-40

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

37Balak said to Balaam, “Did I not send again and again to you to summon you? Why did you not come to me? Am I not able to honor you?”

38Balaam said to Balak, “Look, I have come to you. Now, am I able to speak just anything? I must speak only the word that God puts in my mouth.”

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

40And Balak sacrificed bulls and sheep, and sent some to Balaam, and to the princes who were with him.
