2 Chronicles 20:13-17

And all Judah stood before Jehovah, with their little ones, their wives, and their children. Then 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, came the Spirit of Jehovah in the midst of the assembly; and he said, Hearken ye, all Judah, and ye inhabitants of Jerusalem, and thou king Jehoshaphat: Thus saith Jehovah unto you, Fear not ye, neither be dismayed by reason of this great multitude; for the battle is not yours, but God’s. To-morrow go ye down against them: behold, they come up by the ascent of Ziz; and ye shall find them at the end of the valley, before the wilderness of Jeruel. Ye shall not need to fight in this battle: set yourselves, stand ye still, and see the salvation of Jehovah with you, O Judah and Jerusalem; fear not, nor be dismayed: to-morrow go out against them; for Jehovah is with you.
