20. Early in the morning they went out to the wilderness of Tekoa. As they were going out, Jehoshaphat halted and said: “Listen to me, Judah and inhabitants of Jerusalem! Let your faith in the Lord, your God, be firm, and you will be firm. Have faith in his prophets and you will succeed.”
21. After taking counsel with the people, he appointed some to sing to the Lord and some to praise the holy Splendor as it went forth at the head of the army. They sang: “Give thanks to the Lord, whose love endures forever.”
22. At the moment they began their jubilant praise, the Lord laid an ambush against the Ammonites, Moabites, and those of Mount Seir who were coming against Judah, so that they were defeated.
23. For the Ammonites and Moabites set upon the inhabitants of Mount Seir and exterminated them according to the ban. And when they had finished with the inhabitants of Seir, each helped to destroy the other.
