2 Chronicles 20:1-15

After that, the Moabites and the Ammonites, together with some Meu­­nites, came against Jehoshaphat for battle. And some came and declared this to Jehoshaphat, “A large multitude is coming against you from across the Dead Sea from Edom; and observe, they are in Hazezon Tamar” (that is, En Gedi). Then Jehoshaphat was fearful and set himself to seek the LORD, and he called for a fast throughout all Judah. And Judah was assembled to seek the LORD; even from all the cities of Judah, they came to obtain aid from the LORD. And Jehoshaphat stood in the midst of the assembly of Judah and Jerusalem in the house of the LORD before the new courtyard, and he said: “O LORD God of our fathers, are You not God in the heavens? And do You not rule over all the kingdoms of the nations? In Your hand are strength and might, and there is no one who can oppose You. Did You not, our God, drive out those who lived in this land before Your people Israel, and You gave it perpetually to the descendants of Abraham, who was in covenant love with You. And they have dwelled in it and have built in it for You a sanctuary for Your name saying, ‘If disaster comes upon us, the sword, or judgment, or pestilence, or famine, then we will stand before this temple and before You because Your name is in this temple. And we will cry out to You in our distress, and You will hear and deliver.’ “Now here are the sons of Ammon and Moab and Mount Seir, whom You did not let Israel invade when they came out of the land of Egypt, when they turned away from them and did not destroy them. See how they are rewarding us by coming to drive us out of Your possession, which You have given us to inherit. O our God, will You not render judgment on them? For we have not strength enough to stand before this great army that is coming against us. And we do not know what we should do, but our eyes are on You.” Now all of Judah was standing before the LORD, even their infants, wives, and children. And in the midst of the assembly the Spirit of the LORD came on Jahaziel the son of Zechariah, the son of Benaiah, the son of Jeiel, the son of Mattaniah, a Levite from the line of Asaph. And he said, “Pay attention all Judah, and those dwelling in Jerusalem, and King Jehoshaphat: Thus says the LORD to you, ‘Do not fear, nor be dismayed because of this great army, for the battle is not yours, but God’s.
