17 It will not be you who will fight. Instead, only stand with confidence, and you will see the help of the Lord over you, O Judah and Jerusalem. Do not be afraid. Neither should you be dismayed. Tomorrow you shall go forth against them, and the Lord will be with you."
18 Then Jehoshaphat, and Judah, and all the inhabitants of Jerusalem fell prone on the ground before the Lord, and they adored him.
19 And the Levites from the sons of Kohath, and from the sons of Korah, were praising the Lord, the God of Israel, with a great voice, on high.
20 And when they had risen up in the morning, they went out through the desert of Tekoa. And as they were setting out, Jehoshaphat, standing in their midst, said: "Listen to me, men of Judah and all inhabitants of Jerusalem. Believe in the Lord your God, and you will be secure. Believe in his prophets, and everything will come to prosperity."
21 And he gave counsel to the people. And he appointed the singing men of the Lord, so that they would praise him by their companies, and so that they would go before the army, and with one voice say: "Confess to the Lord. For his mercy is eternal."
22 And when they had begun to sing praises, the Lord turned their ambushes upon themselves, that is, those of the sons of Ammon, and of Moab, and of mount Seir, who had gone forth so that they might fight against Judah. And they were struck down.
23 For the sons of Ammon and of Moab rose up against the inhabitants of mount Seir, so that they might slay and destroy them. And when they had perpetrated this work, now also turning upon themselves, they cut one another with wounds.
