Numbers 22:28-30

28And the Lord opened the mouth of the donkey, and she said to Balaam, “What have I done to you that you have struck me these three times?”

29Then Balaam said to the donkey, “Because you have made a mockery of me! If there had been a sword in my hand, I would have killed you by now!”

30The donkey said to Balaam, “Am I not your donkey on which you have ridden all your life until this day? Have I ever been accustomed to do so to you?” And he said, “No.”
