Numbers 22:20-23

²⁰God came to Balaam at night, and said to him, “If the men have come to call you, rise up, go with them; but only the word which I speak to you, that you shall do.”

²¹Balaam rose up in the morning, and saddled his donkey, and went with the princes of Moab.

²²God’s anger burnt because he went; and the LORD’s angel placed himself in the way as an adversary against him. Now he was riding on his donkey, and his two servants were with him.

²³The donkey saw the LORD’s angel standing in the way, with his sword drawn in his hand; and the donkey turned out of the path, and went into the field. Balaam struck the donkey, to turn her into the path.
