2 Chronicles 20:14-20

ISV(i) 14 The Prophetic Response of JahazielThen the Spirit of the LORD came upon Zechariah’s son Jahaziel, the son of Benaiah, the son of Jeiel, the son of Mattaniah, a descendant of Levi from the descendants of Asaph in the middle of the assembly, and he said: 15 “Pay attention, everyone in Judah, in Jerusalem, and you, too, King Jehoshaphat! This is what the LORD says to you: ‘Stop being afraid, and stop being discouraged because of this vast invasion force, because the battle doesn’t belong to you, but to God. 16 Tomorrow you are to go down to attack them. Pay attention, now—they’ll be coming up near the ascent of Ziz. You’ll find them at the end of the valley that looks out over the Jeruel wilderness. 17 You won’t be fighting in this battle. Take your stand, but stand still, and watch the LORD’s salvation on your behalf, Judah and Jerusalem! Never fear and never be discouraged. Go out to face them tomorrow, since the LORD is with you.’”
18 Jehoshaphat bowed down with his face to the ground, and all the assembled inhabitants of Judah and Jerusalem fell face down in the LORD’s presence and worshipped the LORD. 19 Descendants of Levi from the descendants of Kohath and from the descendants of Korah stood up to praise the LORD God of Israel in a very loud voice that ascended to heaven.
20 Jehoshaphat’s Instructions the Next MorningThe army got up early the next morning and headed out into the wilderness of Tekoa. Jehoshaphat stood up and addressed them. “Listen to me, you inhabitants of Judah and Jerusalem,” he said. “Have faith in the LORD your God and you’ll be established! Have faith in his prophets and you’ll succeed!”
