Numbers 22:20-22

American Standard Version

²⁰ And God came unto Balaam at night, and said unto him, If the men are come to call thee, rise up, go with them; but only the word which I speak unto thee, that shalt thou do.

²¹ And Balaam rose up in the morning, and saddled his ass, and went with the princes of Moab. ²² And God’s anger was kindled because he went; and the angel of Jehovah placed himself in the way for an adversary against him. Now he was riding upon his ass, and his two servants were with him.
