2 Chronicles 20:1-15

After this the Moabites and Ammonites, and with them some of the Meunites, came against Jehoshaphat for battle. Some men came and told Jehoshaphat, “A great multitude is coming against you from Edom, from beyond the sea; and, behold, they are in Hazazon-tamar” (that is, Engedi). Then Jehoshaphat was afraid and set his face to seek the LORD, and proclaimed a fast throughout all Judah. And Judah assembled to seek help from the LORD; from all the cities of Judah they came to seek the LORD. 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? You rule over all the kingdoms of the nations. In your hand are power and might, so that none is able to withstand you. Did you not, our God, drive out the inhabitants of this land before your people Israel, and give it forever to the descendants of Abraham your friend? And they have lived in it and have built for you in it a sanctuary for your name, saying, ‘If disaster comes upon us, the sword, judgment, or pestilence, or famine, we will stand before this house and before you—for your name is in this house—and cry out to you in our affliction, and you will hear and save.’ And now behold, the men of Ammon and Moab and Mount Seir, whom you would not let Israel invade when they came from the land of Egypt, and whom they avoided 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 execute judgment on them? For we are powerless against this great horde that is coming against us. We do not know what to do, but our eyes are on you.” Meanwhile all Judah stood before the LORD, with their little ones, their wives, and their children. And the Spirit of the LORD came upon Jahaziel the son of Zechariah, son of Benaiah, son of Jeiel, son of Mattaniah, a Levite of the sons of Asaph, in the midst of the assembly. And he said, “Listen, all Judah and inhabitants of Jerusalem and King Jehoshaphat: Thus says the LORD to you, ‘Do not be afraid and do not be dismayed at this great horde, for the battle is not yours but God’s.
