Numbers 22:22-27

Then God’s anger was aroused because he went, and the Angel of the LORD took His stand in the way as an adversary against him. And he was riding on his donkey, and his two servants were with him. Now the donkey saw the Angel of the LORD standing in the way with His drawn sword in His hand, and the donkey turned aside out of the way and went into the field. So Balaam struck the donkey to turn her back onto the road. Then the Angel of the LORD stood in a narrow path between the vineyards, with a wall on this side and a wall on that side. And when the donkey saw the Angel of the LORD, she pushed herself against the wall and crushed Balaam’s foot against the wall; so he struck her again. Then the Angel of the LORD went further, and stood in a narrow place where there was no way to turn either to the right hand or to the left. And when the donkey saw the Angel of the LORD, she lay down under Balaam; so Balaam’s anger was aroused, and he struck the donkey with his staff.
