Numbers 22:25-28

²⁵and the ass seeth the messenger of Jehovah, and is pressed unto the wall, and presseth Balaam's foot unto the wall, and he addeth to smite her;

²⁶and the messenger of Jehovah addeth to pass over, and standeth in a strait place where there is no way to turn aside — right or left —

²⁷and the ass seeth the messenger of Jehovah, and croucheth under Balaam, and the anger of Balaam burneth, and he smiteth the ass with a staff.

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