2 Chronicles 20:14-19

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. Tomorrow go down against them. Behold, they will come up by the ascent of Ziz, and you will find them at the end of the valley in front of the wilderness of Jeruel. You need not fight in this battle; station yourselves, stand and see the salvation of the LORD on your behalf, O Judah and Jerusalem.’ Do not fear or be dismayed; tomorrow go out to face them, for the LORD is with you.” Jehoshaphat bowed his head with his face to the ground, and all Judah and the inhabitants of Jerusalem fell down before the LORD, worshiping the LORD. The Levites, from the sons of the Kohathites and of the sons of the Korahites, stood up to praise the LORD God of Israel, with a very loud voice.
