After this the Moabites, the Ammonites, and with them the Meunites came against Jehoshaphat to battle. It was told Jehoshaphat, “A great multitude has come against you from beyond the [Dead] Sea, from Edom; and behold they are in Hazazon-tamar, which is En-gedi.” Then Jehoshaphat feared, and set himself [determinedly, as his vital need] to seek the LORD; he proclaimed a fast in all Judah.
And Judah gathered together to ask help from the LORD; even out of all the cities of Judah they came to seek the Lord [yearning for Him with all their desire]. And Jehoshaphat stood in the assembly of Judah and Jerusalem in the house of the Lord before the new court and said, “O LORD, God of our fathers, are You not God in heaven? And do You not rule over all the kingdoms of the nations? In Your hand are power and might, so that none is able to withstand You. Did not You, O our God, drive out the inhabitants of this land before Your people Israel and give it forever to the descendants of Abraham Your friend? They dwelt in it and have built You a sanctuary in it for Your Name, saying, ‘If evil comes upon us, the sword of judgment, or pestilence, or famine, we will stand before this house and before You–for Your Name [and the symbol of Your presence] is in this house–and cry to You in our affliction, and You will hear and save.’ And now behold, the men of Ammon, Moab, and Mount Seir, whom You would not let Israel invade when they came from the land of Egypt, and whom they turned from and did not destroy – Behold, they reward us by coming to drive us out of Your possession which You have given us to inherit. O our God, will You not exercise judgment upon them? For we have no might to stand against this great company that is coming against us. We do not know what to do, but our eyes are upon You.”
And all Judah stood before the LORD, with their children and their wives. Then the Spirit of the LORD came upon Jahaziel son of Zechariah, the son of Benaiah, the son of Jeiel, the son of Mattaniah, a Levite of the sons of Asaph, in the midst of the assembly. He said, “Hearken, all Judah, you inhabitants of Jerusalem, and you King Jehoshaphat. The LORD says this to you: ‘Be not afraid or dismayed at this great multitude; for the battle is not yours, but God’s. Tomorrow go down to them. Behold, they will come up by the Ascent of Ziz, and you will find them at the end of the ravine before the Wilderness of Jeruel. You shall not need to fight in this battle; take your positions, stand still, and see the deliverance of the LORD [Who is] with you, O Judah and Jerusalem. Fear not nor be dismayed. Tomorrow go out against them, for the LORD is with you.'”
And Jehoshaphat bowed his head with his face to the ground, and all Judah and the inhabitants of Jerusalem fell down before the LORD, worshiping Him. And some Levites of the Kohathites and Korahites stood up to praise the LORD, the God of Israel, with a very loud voice. And they rose early in the morning and went out into the Wilderness of Tekoa; and as they went out, Jehoshaphat stood and said, “Hear me, O Judah, and you inhabitants of Jerusalem! Believe in the LORD your God and you shall be established; believe and remain steadfast to His prophets and you shall prosper.”
When he had consulted with the people, he appointed singers to sing to the LORD and praise Him in their holy [priestly] garments as they went out before the army, saying, “Give thanks to the LORD, for His mercy and loving-kindness endure forever!” And when they began to sing and to praise, the LORD set ambushments against the men of Ammon, Moab, and Mount Seir who had come against Judah, and they were [self-] slaughtered; for [suspecting betrayal] the men of Ammon and Moab rose against those of Mount Seir, utterly destroying them. And when they had made an end of the men of Seir, they all helped to destroy one another. And when Judah came to the watchtower of the wilderness, they looked at the multitude, and behold, they were dead bodies fallen to the earth, and none had escaped!
(2 Chronicles 20:1-24)
For the weapons of our warfare are not physical [weapons of flesh and blood], but they are mighty before God for the overthrow and destruction of strongholds.
(2 Corinthians 10:4)
