'Riding' in the Bible

At this, the anger of the LORD flared up against Balaam, because he was leaving. So the angel of the LORD stood in the way to oppose him. As Balaam was riding his donkey, accompanied by two of his servants,

But in response, the donkey asked Balaam, "I'm your donkey that you've ridden on in the past without incident, am I not, and I'm the same donkey you're riding on right now, am I not? Am I in the habit of treating you like this?" "No," he admitted.
