Numbers 22:25-29

²⁵And the ass saw the Angel of Jehovah, and she pressed herself against the wall, and crushed Balaam's foot against the wall; and he smote her again.

²⁶Then the Angel of Jehovah went still further, and stood in a narrow place, where was no way to turn either to the right hand or to the left.

²⁷And the ass saw the Angel of Jehovah, and lay down under Balaam; and Balaam's anger was kindled, and he smote the ass with his staff.

²⁸And Jehovah opened the mouth of the ass, and she said to Balaam, What have I done to thee, that thou hast smitten me these three times?

²⁹And Balaam said to the ass, Because thou hast mocked me: I would there were a sword in my hand, for now would I kill thee!
