Numbers 22:21 KJV

19Now therefore, I pray you, tarry ye also here this night, that I may know what the LORD will say unto me more.

20And God came unto Balaam at night, and said unto him, If the men come to call thee, rise up, and go with them; but yet the word which I shall say unto thee, that shalt thou do.

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

22And God’s anger was kindled because he went: and the angel of the LORD stood in the way for an adversary against him. Now he was riding upon his ass, and his two servants were with him.

23And the ass saw the angel of the LORD standing in the way, and 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.
