Numbers 22:28-30

And Jehovah opened the mouth of the ass, and she said unto Balaam, What have I done unto thee, that thou hast smitten me these three times? And Balaam said unto the ass, Because thou hast mocked me: I would there were a sword in my hand, for now I had killed thee. And the ass said unto Balaam, Am not I thine ass, upon which thou hast ridden all thy life long unto this day? was I ever wont to do so unto thee? and he said, Nay.
