Numbers 22:31

28 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?

29 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.

30 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.

31 Then Jehovah opened the eyes of Balaam, and he saw the angel of Jehovah standing in the way, with his sword drawn in his hand; and he bowed his head, and fell on his face.

32 And the angel of Jehovah said unto him, Wherefore hast thou smitten thine ass these three times? behold, I am come forth for an adversary, because thy way is perverse before me:

33 and the ass saw me, and turned aside before me these three times: unless she had turned aside from me, surely now I had even slain thee, and saved her alive.

34 And Balaam said unto the angel of Jehovah, I have sinned; for I knew not that thou stoodest in the way against me: now therefore, if it displease thee, I will get me back again.
