Numbers 22:25

And when the ass saw the angel of the Lord
In the same position as before, with a drown sword in his hand, and being frightened again, and in a narrow path, and no way to turn aside:

she thrust herself unto the wall;
to one of the walls, as close as she could, in order to get by the angel:

and crushed Balaam's foot against the wall;
running up so very closely to it:

and he smote her again;
having done it once before, ( Numbers 22:23 ) the times of smiting are observed, for the sake of what the ass after said, and for the confirmation of it.
