2 Chronicles 20:1; 2 Chronicles 20:10; 2 Chronicles 20:22-23
Now it came about after this that the sons of Moab and the sons of Ammon, together with some of the Meunites, came to make war against Jehoshaphat.
"Now behold, the sons of Ammon and Moab and Mount Seir, whom You did not let Israel invade when they came out of the land of Egypt (they turned aside from them and did not destroy them),
When they began singing and praising, the LORD set ambushes against the sons of Ammon, Moab and Mount Seir, who had come against Judah; so they were routed.
For the sons of Ammon and Moab rose up against the inhabitants of Mount Seir destroying them completely; and when they had finished with the inhabitants of Seir, they helped to destroy one another.
