Numbers 22:35-39

³⁵The angel said, Go thou with these men, but beware, that thou speak not any other thing than I shall command to thee. Therefore Balaam went with the princes.

³⁶And when Balak heard that Balaam was nigh, he went out into the coming of him, in Ar, the city of Moabites, which is set in the last coast of Arnon.

³⁷And Balak said to Balaam, I sent messengers to call thee; why camest thou not anon to me? whether for I may not yield meed to thy coming?

³⁸To whom Balaam answered, Lo! I am present, whether I shall be able to speak other thing than that, that God shall put in my mouth?

³⁹Therefore they went forth together, and they came into a city, which was in the last coast of his realm.
