Numbers 22:27-31

27And when the donkey saw the angel of the LORD, she fell down under Balaam: and Balaam’s anger was kindled, and he smote the donkey with a staff. 28And the LORD opened the mouth of the donkey, and she said to Balaam, What have I done to thee, that thou hast smitten me these three times? 29And Balaam said to the donkey, Because thou hast mocked me: I would there were a sword in my hand, for now would I kill thee. 30And the donkey said to Balaam, Am not I thy donkey, upon which thou hast rid ever since I was thine to this day? was I ever accustomed to do so to thee? And he said, Nay.12 31Then the LORD opened the eyes of Balaam, and he saw the angel of the LORD standing in the way, and his sword drawn in his hand: and he bowed down his head, and fell flat on his face.3
