Numbers 22:35-36

³⁵But the angel replied, “I will allow you to go with these men, but you must say only what I tell you to say!” So Balaam went on with the leaders whom Balak had sent.

³⁶When King Balak heard that Balaam was coming, he went to meet him at a Moab town alongside the Arnon River that was at the border of his own land.
