Numbers 22:20-22

King James Version

²⁰ And God came unto Balaam at night, and said unto him, If the men come to call thee, rise up, and go with them; but yet the word which I shall say 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 the Lord stood in the way for an adversary against him. Now he was riding upon his ass, and his two servants were with him.
