2 Chronicles 20:14-20

MLV(i) 14 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.
15 And he said, Listen, all Judah and you* inhabitants of Jerusalem and you king Jehoshaphat. Thus Jehovah says to you*, Do not fear, neither be dismayed because of this great multitude. For the battle is not yours*, but God's. 16 Tomorrow go down against them. Behold, they come up by the Ascent of Ziz. And you* will find them at the end of the valley, before the wilderness of Jeruel.
17 You* will not need to fight in this battle. Set yourselves, stand still and see the salvation of Jehovah with you*, O Judah and Jerusalem. Do not fear, nor be dismayed. Tomorrow go out against them, for Jehovah is with you*.
18 And Jehoshaphat bowed his head with his face to the ground. And all Judah and the inhabitants of Jerusalem fell down before Jehovah, worshiping Jehovah. 19 And the Levites, of the sons of the Kohathites and of the sons of the Korahites, stood up to praise Jehovah, the God of Israel, with an exceedingly loud voice.
20 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 you* inhabitants of Jerusalem. Believe in Jehovah your* God, so you* will be established. Believe his prophets, so you* will prosper.
