2 Chronicles 20:4-15

So Judah gathered together to seek help from the LORD; they even came from all the cities of Judah to seek the LORD. Then Jehoshaphat stood in the assembly of Judah and Jerusalem, in the house of the LORD before the new court, and he said, “O LORD, the God of our fathers, are You not God in the heavens? And are You not ruler over all the kingdoms of the nations? Power and might are in Your hand so that no one can stand against You. Did You not, O our God, drive out the inhabitants of this land before Your people Israel and give it to the descendants of Abraham Your friend forever? They have lived in it, and have built You a sanctuary there for Your name, saying, ‘Should evil come upon us, the sword, or judgment, or pestilence, or famine, we will stand before this house and before You (for Your name is in this house) and cry to You in our distress, and You will hear and deliver us.’ Now behold, 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 (they turned aside from them and did not destroy them), see how they are rewarding us by coming to drive us out from Your possession which You have given us as an inheritance. O our God, will You not judge them? For we are powerless before this great multitude who are coming against us; nor do we know what to do, but our eyes are on You.” All Judah was standing 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, the Levite of the sons of Asaph; and he said, “Listen, all Judah and the inhabitants of Jerusalem and King Jehoshaphat: thus says the LORD to you, ‘Do not fear or be dismayed because of this great multitude, for the battle is not yours but God’s.
