Numbers 22:27-31

27When the donkey saw the angel of the Lord, she lay down under Balaam; so 1Balaam was angry and struck the donkey with his stick. 28And 2the 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, 3I would have killed you by now.” 30The donkey said to Balaam, “Am I not your donkey on which you have ridden all your life to this day? Have I ever been accustomed to do so to you?” And he said, “No.”

31Then the Lord opened the eyes of Balaam, and he saw 4the angel of the Lord standing in the way with his drawn sword in his hand; and he bowed 5all the way to the ground.
