So, in Numbers 22, Balak, King of Moab, has a real beef with the Israelites. He calls in Balaam the prophet to put a stop to them. Balaam and Balak go on a road trip to a few different places, but Balaam's donkey keeps messing up their plans by turning off the road and refusing to move. Finally, Balaam realizes the donkey is actually seeing an angel blocking their way and stops trying. After that, Balaam blesses the Israelites instead of cursing them, and Balak is not happy. In the end, Balak goes home, and Balaam goes to a party with the Israelites. I guess that's a lesson: don't mess with the Israelites!
