2 Chronicles 20:1-18

Now it happened after this that the Moabites and the Ammonites, together with some of the Meunites, came to make war against Jehoshaphat. Then it was reported to Jehoshaphat, “A great multitude has come against you from beyond the [Dead] Sea, out of Aram (Syria); and behold, they are in Hazazon-tamar (that is, Engedi).” Then Jehoshaphat was afraid and set himself [determinedly, as his vital need] to seek the LORD; and he proclaimed a fast throughout all Judah. So [the people of] Judah gathered together to seek help from the LORD; indeed they came from all the cities of Judah to seek the LORD [longing for Him with all their heart]. Then Jehoshaphat stood in the assembly of Judah and Jerusalem, in the house of the LORD in front of the new courtyard, 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? Power and might are in Your hand, there is no one able to take a stand against You. O our God, did You not drive out the inhabitants of this land before Your people Israel and give it forever to the descendants of Your friend Abraham? They have lived in it, and have built You a sanctuary in it for Your Name, saying, ‘If evil comes on us, or the sword of judgment, or plague, or famine, we will stand before this house and before You (for Your Name and Your Presence is in this house) and we will cry out to You in our distress, and You will hear and save us.’ Now behold, the sons of Ammon and Moab and Mount Seir, whom You would not allow Israel to invade when they came from the land of Egypt (for they turned away from them and did not destroy them), [Deut 2:9] here they are, rewarding us by coming to drive us out of Your possession which You have given us as an inheritance. O our God, will You not judge them? For we are powerless against this great multitude which is coming against us. We do not know what to do, but our eyes are on You.” So all Judah stood before the LORD, with their infants, their wives, and their children. Then in the midst of the assembly the Spirit of the LORD came upon Jahaziel the son of Zechariah, the son of Benaiah, the son of Jeiel, the son of Mattaniah, a Levite of the sons of Asaph. He said, “Listen carefully, all [you people of] Judah, and you inhabitants of Jerusalem, and 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. Go down against them tomorrow. Behold, they will come up by the ascent of Ziz, and you will find them at the end of the river valley, in front of the Wilderness of Jeruel. You need not fight in this battle; take your positions, stand and witness the salvation of the LORD who is with you, O Judah and Jerusalem. Do not fear or be dismayed; tomorrow go out against them, for the LORD is with you.’ ” Jehoshaphat bowed with his face to the ground, and all Judah and the inhabitants of Jerusalem fell down before the LORD, worshiping Him.
