Numbers 22:36-40

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

37Balak asked Balaam, “Did I not send you an urgent summons? Why didn’t you come to me? Am I really not able to reward you?”

38Balaam said to him, “Look, I have come to you, but can I say anything I want? I must speak only the message God puts in my mouth.”

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

40Balak sacrificed cattle, sheep, and goats and sent for Balaam and the officials who were with him.
