2 Chronicles 20:19-20

Then the Levites from the clans of Kohath and Korah stood to praise the LORD, the God of Israel, with a very loud shout. Early the next morning the army of Judah went out into the wilderness of Tekoa. On the way Jehoshaphat stopped and said, “Listen to me, all you people of Judah and Jerusalem! Believe in the LORD your God, and you will be able to stand firm. Believe in his prophets, and you will succeed.”
