Numbers 22:22-23

²²and the anger of God burneth because he is going, and a messenger of Jehovah stationeth himself in the way for an adversary to him, and he is riding on his ass, and two of his servants [are] with him,

²³and the ass seeth the messenger of Jehovah standing in the way, and his drawn sword in his hand, and the ass turneth aside out of the way, and goeth into a field, and Balaam smiteth the ass to turn it aside into the way.
