Numbers 22:35-39

³⁵The angel said: Go with these men, and see thou speak no other thing than what I shall command thee. He went therefore with the princes.

³⁶And when Balac heard it he came forth to meet him in a town of the Moabites, that is situate in the uttermost borders of Arnon.

³⁷And he said to Balaam: I sent messengers to call thee, why didst thou not come immediately to me? was it because I am not able to reward thy coming?

³⁸He answered him: Lo, here I am: shall I have power to speak any other thing but that which God shall put in my mouth?

³⁹So they went on together, and came into a city, that was in the uttermost borders of his kingdom.
