Numbers 22
20 Ref God came to Balaam at night, and said to him, If the men are come to call you, rise up, go with them; but only the word which I speak to you, that shall you do.
21 Ref Balaam rose up in the morning, and saddled his donkey, and went with the princes of Moab.
22 Ref God's anger was kindled because he went; and the angel of Yahweh placed himself in the way for an adversary against him. Now he was riding on his donkey, and his two servants were with him.
