Numbers 22:16-25

And they came to Balaam, and said to him, Thus saith Balak the son of Zippor, Let nothing, I pray thee, hinder thee from coming unto me: for I will promote thee unto very great honor, and whatsoever thou sayest unto me I will do: come therefore, I pray thee, curse me this people. And Balaam answered and said unto the servants of Balak, If Balak would give me his house full of silver and gold, I cannot go beyond the word of Jehovah my God, to do less or more. Now therefore, I pray you, tarry ye also here this night, that I may know what Jehovah will speak unto me more. And God came unto Balaam at night, and said unto him, If the men are come to call thee, rise up, go with them; but only the word which I speak unto thee, that shalt thou do. And Balaam rose up in the morning, and saddled his ass, and went with the princes of Moab. And God’s anger was kindled because he went; and the angel of Jehovah placed himself in the way for an adversary against him. Now he was riding upon his ass, and his two servants were with him. And the ass saw the angel of Jehovah standing in the way, with his sword drawn in his hand; and the ass turned aside out of the way, and went into the field: and Balaam smote the ass, to turn her into the way. Then the angel of Jehovah stood in a narrow path between the vineyards, a wall being on this side, and a wall on that side. And the ass saw the angel of Jehovah, and she thrust herself unto the wall, and crushed Balaam’s foot against the wall: and he smote her again.
