Numbers 22:8-9, 31-35

“Stay here overnight,” Balaam said. “In the morning I will tell you whatever the LORD directs me to say.” So the officials from Moab stayed there with Balaam. That night God came to Balaam and asked him, “Who are these men visiting you?”

Then the LORD opened Balaam’s eyes, and he saw the angel of the LORD standing in the roadway with a drawn sword in his hand. Balaam bowed his head and fell face down on the ground before him. “Why did you beat your donkey those three times?” the angel of the LORD demanded. “Look, I have come to block your way because you are stubbornly resisting me. Three times the donkey saw me and shied away; otherwise, I would certainly have killed you by now and spared the donkey.” Then Balaam confessed to the angel of the LORD, “I have sinned. I didn’t realize you were standing in the road to block my way. I will return home if you are against my going.” But the angel of the LORD told Balaam, “Go with these men, but say only what I tell you to say.” So Balaam went on with Balak’s officials.
