2 Chronicles 20:15-30

He said, “Listen, everyone from Judah, people of Jerusalem, and King Jehoshaphat. This is what the Lord has to say to you: Don't be afraid or discouraged because of this large army. This isn't your battle—it's God's! Tomorrow march down to face them. You will see them coming up the pass at Ziz—you'll find them at the end of the valley in front of the desert of Jeruel. But you do not need to fight this battle. Just stand still and watch the Lord's victory. He is with you, Judah and Jerusalem! Don't be afraid or discouraged! March down to face them, for the Lord is with you!” Jehoshaphat bowed down with his face to the ground, and all the people of Judah and Jerusalem fell to the ground before the Lord, worshiping him. Then the Levites from the Kohathites and Korahites stood to praise the Lord, the God of Israel, shouting loudly. They got up early the next morning and went to the desert of Tekoa. As they left, Jehoshaphat stood up and said, “Listen to me, people of Judah and Jerusalem. Trust in the Lord your God, and you will be vindicated; trust in his prophets, and you will be successful.” After discussion with the people, he appointed singers to praise the Lord for his glorious, holy goodness. They led the way at the front of the army, singing, “Praise the Lord, for his trustworthy love lasts forever!” As soon as they started singing and praising, the Lord ambushed the men of Ammon, Moab, and Mount Seir who were coming to attack Judah, and they were defeated. The men of Ammon and Moab turned on the men from Mount Seir, killing all of them. Once they'd finished wiping out the army from Seir, they turned on each other, destroying themselves. So when the men of Judah came to the watchtower in the desert, they looked out to see the enemy army and all they saw were corpses lying on the ground! No one had escaped. When Jehoshaphat and his people came to collect the plunder, they found a great deal of cattle, equipment, clothing, and other valuable articles, more than they could carry. It took three days to collect the plunder because there was so much of it. On the fourth day they gathered in the Valley of Blessing. They gave it this name because this was where they blessed the Lord. It is still called the Valley of Blessing to this day. Then all the men of Judah and Jerusalem celebrated as they returned to Jerusalem, with Jehoshaphat leading them, full of joy for the Lord's victory over their enemies. They entered Jerusalem and went straight to the Temple of the Lord, accompanied by music from harps, lyres, and trumpets. All the kingdoms around were in awe of God when they heard that the Lord had fought against the enemies of Israel. Jehoshaphat and his kingdom were at peace, for God gave him rest—there were no attacks from any direction.
