2 Chronicles 20:12-20

O our God, wilt thou not judge them? for we have no might against this great company that cometh against us; neither know we what to do: but our eyes are upon thee. 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. And Jehoshaphat bowed his head with his face to the ground; and all Judah and the inhabitants of Jerusalem fell down before Jehovah, worshipping Jehovah. And the Levites, of the children of the Kohathites and of the children of the Korahites, stood up to praise Jehovah, the God of Israel, with an exceeding loud voice. And they rose early in the morning, and went forth into the wilderness of Tekoa: and as they went forth, Jehoshaphat stood and said, Hear me, O Judah, and ye inhabitants of Jerusalem: believe in Jehovah your God, so shall ye be established; believe his prophets, so shall ye prosper.
