Numbers 22:35

The LORD’s angel said to him, “Why have you struck your donkey these three times? Behold, I have come out as an adversary, because your way is perverse before me.

The donkey saw me, and turned away before me these three times. Unless she had turned away from me, surely now I would have killed you, and saved her alive.”

Balaam said to the LORD’s angel, “I have sinned; for I didn’t know that you stood in the way against me. Now therefore, if it displeases you, I will go back again.”

When Balak heard that Balaam had come, he went out to meet him to the City of Moab, which is on the border of the Arnon, which is in the utmost part of the border.

Balak said to Balaam, “Didn’t I earnestly send for you to summon you? Why didn’t you come to me? Am I not able indeed to promote you to honor?”

Balaam said to Balak, “Behold, I have come to you. Have I now any power at all to speak anything? I will speak the word that God puts in my mouth.”
