20After this the Moabites and Ammonites, and with them some of the Meunites, came against Jehoshaphat for battle. 2Messengers came and told Jehoshaphat, A great multitude is coming against you from Edom, from beyond the sea; already they are at Hazazon-tamar (that is, En-gedi). 3Jehoshaphat was afraid; he set himself to seek the Lord, and proclaimed a fast throughout all Judah. 4Judah assembled to seek help from the Lord; from all the towns of Judah they came to seek the Lord.
5 Jehoshaphat stood in the assembly of Judah and Jerusalem, in the house of the Lord, before the new court, 6and said, O Lord, God of our ancestors, are you not God in heaven? Do you not rule over all the kingdoms of the nations? In your hand are power and might, so that no one is able to withstand you. 7Did you not, O our God, drive out the inhabitants of this land before your people Israel, and give it for ever to the descendants of your friend Abraham? 8They have lived in it, and in it have built you a sanctuary for your name, saying, 9If disaster comes upon us, the sword, judgement, or pestilence, or famine, we will stand before this house, and before you, for your name is in this house, and cry to you in our distress, and you will hear and save. 10See now, the people of Ammon, Moab, and Mount Seir, whom you would not let Israel invade when they came from the land of Egypt, and whom they avoided and did not destroy 11they reward us by coming to drive us out of your possession that you have given us to inherit. 12O our God, will you not execute judgement upon them? For we are powerless against this great multitude that is coming against us. We do not know what to do, but our eyes are on you.
13 Meanwhile all Judah stood before the Lord, with their little ones, their wives, and their children. 14Then the spirit of the Lord came upon Jahaziel son of Zechariah, son of Benaiah, son of Jeiel, son of Mattaniah, a Levite of the sons of Asaph, in the middle of the assembly. 15He said, Listen, all Judah and inhabitants of Jerusalem, and King Jehoshaphat: Thus says the Lord to you: Do not fear or be dismayed at this great multitude; for the battle is not yours but Gods. 16Tomorrow go down against them; they will come up by the ascent of Ziz; you will find them at the end of the valley, before the wilderness of Jeruel. 17This battle is not for you to fight; take your position, stand still, and see the victory of the Lord on your behalf, O Judah and Jerusalem. Do not fear or be dismayed; tomorrow go out against them, and the Lord will be with you.
18 Then Jehoshaphat bowed down with his face to the ground, and all Judah and the inhabitants of Jerusalem fell down before the Lord, worshipping the Lord. 19And the Levites, of the Kohathites and the Korahites, stood up to praise the Lord, the God of Israel, with a very loud voice.
20 They rose early in the morning and went out into the wilderness of Tekoa; and as they went out, Jehoshaphat stood and said, Listen to me, O Judah and inhabitants of Jerusalem! Believe in the Lord your God and you will be established; believe his prophets.
21When he had taken counsel with the people, he appointed those who were to sing to the Lord and praise him in holy splendour, as they went before the army, saying,
Give thanks to the Lord,
for his steadfast love endures for ever.
22As they began to sing and praise, the Lord set an ambush against the Ammonites, Moab, and Mount Seir, who had come against Judah, so that they were routed. 23For the Ammonites and Moab attacked the inhabitants of Mount Seir, destroying them utterly; and when they had made an end of the inhabitants of Seir, they all helped to destroy one another.
