Sometime after these events, the Moabites and the Ammonites, accompanied by some other descendants of Ammon, attacked Jehoshaphat and started a war.

Now therefore look! The Ammonites, the Moabites, and the inhabitants of Mount Seir, whom you would not permit Israel to attack when they arrived from the land of Egypt since they turned away from them and did not eliminate them

Right on time, as they began to sing and praise, the LORD ambushed the Ammonites, Moabites, and the inhabitants of Mount Seir who had attacked Judah, and they were defeated.

The Ammonites and Moabites attacked the inhabitants of Mount Seir, destroying them, and after they had finished with the inhabitants of Mount Seir, they worked on destroying one another!

The conspirators included Shimeath the Ammonite's son Zabad and Shimrith the Moabite's son Jehozabad.
