2 Chronicles 20:18-29

Jehoshaphat bowed with his face to the ground, and all Judah and the inhabitants of Jerusalem fell down before the LORD, worshiping Him. The Levites, from the sons of the Kohathites and the sons of the Korahites, stood up to praise the LORD God of Israel, with a very loud voice. So they got up 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 and trust in the LORD your God and you will be established (secure). Believe and trust in His prophets and succeed.” When he had consulted with the people, he appointed those who sang to the LORD and those who praised Him in their holy (priestly) attire, as they went out before the army and said, “Praise and give thanks to the LORD, for His mercy and lovingkindness endure forever.” When they began singing and praising, the LORD set ambushes against the sons of Ammon, Moab, and Mount Seir, who had come against Judah; so they were struck down [in defeat]. For the sons of Ammon and Moab [suspecting betrayal] rose up against the inhabitants of Mount Seir, completely destroying them; and when they had finished with the inhabitants of Seir, they helped to destroy one another. When [the men of] Judah came to the lookout tower of the wilderness, they looked toward the multitude, and behold, they were dead bodies lying on the ground, and no one had escaped. When Jehoshaphat and his people came to take their spoil, they found much among them, including equipment, garments, and valuable things which they took for themselves, more than they could carry away; so much that they spent three days gathering the spoil. Then on the fourth day they assembled in the Valley of Beracah, for it was there that they blessed the LORD. For that reason they named that place “The Valley of Beracah (blessing)” until today. Then they returned to Jerusalem with joy, every man of Judah and Jerusalem, led by Jehoshaphat, for the LORD had made them rejoice over their enemies. They came to Jerusalem with harps, lyres, and trumpets to the house (temple) of the LORD. And the fear of God came on all the kingdoms of those countries when they heard that the LORD had fought against the enemies of Israel.
