Numbers 22:31-36

³¹And God opened the eyes of Balaam, and he sees the angel of the Lord withstanding him in the way, and his sword drawn in his hand, and he stooped down and worshipped on his face.

³²And the angel of God said to him, Why have you struck your ass this third time? and, behold, I came out to withstand you, for your way was not seemly before me; and when the ass saw me, she turned away from me this third time.

³³And if she had not turned out of the way, surely now, I should have slain you, and should have saved her alive.

³⁴And Balaam said to the angel of the Lord, I have sinned, for I did not know that you were standing opposite in the way to meet me; and now if it shall not be pleasing to you for me to go on, I will return.

³⁵And the angel of the Lord said to Balaam, Go with the men: nevertheless the word which I shall speak to you, that you shall take heed to speak. And Balaam went with the princes of Balac.

³⁶And when Balac heard that Balaam was come, he went out to meet him, to a city of Moab, which is on the borders of Arnon, which is on the extreme part of the borders.
