Numbers 22:23-25

King James Version

²³ And the ass saw the angel of the Lord standing in the way, and his sword drawn in his hand: and the ass turned aside out of the way, and went into the field: and Balaam smote the ass, to turn her into the way.

²⁴ But the angel of the Lord stood in a path of the vineyards, a wall being on this side, and a wall on that side.

²⁵ And when the ass saw the angel of the Lord, she thrust herself unto the wall, and crushed Balaam's foot against the wall: and he smote her again.
