Numbers 22:30-34

The 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.” Then the LORD opened the eyes of Balaam, and he saw the angel of the LORD standing in the way with his drawn sword in his hand; and he bowed all the way to the ground. The angel of the LORD said to him, “Why have you struck your donkey these three times? Behold, I have come out as an adversary, because your way was contrary to me. But the donkey saw me and turned aside from me these three times. If she had not turned aside from me, I would surely have killed you just now, and let her live.” Balaam said to the angel of the LORD, “I have sinned, for I did not know that you were standing in the way against me. Now then, if it is displeasing to you, I will turn back.”
