Numbers 22:21-25

²¹Balaam got up in the morning, saddled his donkey, and went with the leaders of Moab.

²²But because he went, God's anger was kindled. The angel of Yahweh placed himself in the road as someone hostile to Balaam, who was riding on his donkey. Balaam's two servants were also with him.

²³The donkey saw the angel of Yahweh standing in the road with his drawn sword in his hand. The donkey turned off the road and went into a field. Balaam struck the donkey to turn her back to the road.

²⁴Then the angel of Yahweh stood in a narrow part of the road between some vineyards, with a wall on his right side and another wall on his left side.

²⁵The donkey saw the angel of Yahweh again. She went against the wall and pinned Balaam's foot against it. Balaam struck her again.
