2 Chronicles 20:13-24

Everyone in Judah was there—little children, wives, sons—all present and attentive to GOD. Then Jahaziel was moved by the Spirit of GOD to speak from the midst of the congregation. (Jahaziel was the son of Zechariah, the son of Benaiah, the son of Jeiel, the son of Mattaniah the Levite of the Asaph clan.) He said, “Attention everyone—all of you from out of town, all you from Jerusalem, and you King Jehoshaphat—GOD’s word: Don’t be afraid; don’t pay any mind to this vandal horde. This is God’s war, not yours. Tomorrow you’ll go after them; see, they’re already on their way up the slopes of Ziz; you’ll meet them at the end of the ravine near the wilderness of Jeruel. You won’t have to lift a hand in this battle; just stand firm, Judah and Jerusalem, and watch GOD’s saving work for you take shape. Don’t be afraid, don’t waver. March out boldly tomorrow—GOD is with you.” Then Jehoshaphat knelt down, bowing with his face to the ground. All Judah and Jerusalem did the same, worshiping GOD. The Levites (both Kohathites and Korahites) stood to their feet to praise GOD, the God of Israel; they praised at the top of their lungs! They were up early in the morning, ready to march into the wilderness of Tekoa. As they were leaving, Jehoshaphat stood up and said, “Listen Judah and Jerusalem! Listen to what I have to say! Believe firmly in GOD, your God, and your lives will be firm! Believe in your prophets and you’ll come out on top!” After talking it over with the people, Jehoshaphat appointed a choir for GOD; dressed in holy robes, they were to march ahead of the troops, singing, Give thanks to GOD, His love never quits. As soon as they started shouting and praising, GOD set ambushes against the men of Ammon, Moab, and Mount Seir as they were attacking Judah, and they all ended up dead. The Ammonites and Moabites mistakenly attacked those from Mount Seir and massacred them. Then, further confused, they went at each other, and all ended up killed. As Judah came up over the rise, looking into the wilderness for the horde of barbarians, they looked on a killing field of dead bodies—not a living soul among them.
