2 Chronicles 20:14-17

14Then in the midst of the congregation, the Ruach Adonai came upon Jahaziel son of Zechariah, son of Benaiah, son of Jeiel, son of Mattaniah the Levite, of the sons of Asaph,

15and he said: “Listen all Judah and inhabitants of Jerusalem and King Jehoshaphat. Thus Adonai says to you, ‘Do not be afraid or be dismayed because of this great multitude, for the battle is not yours, but God’s.

16Tomorrow go down against them as they come up the ascent of Ziz. You will find them at the end of the valley in front of the wilderness of Jeruel.

17You will not fight in this battle. Take your positions, stand and see the salvation of Adonai with you, O Judah and Jerusalem. Do not be afraid or be dismayed. Tomorrow go out to face them, for Adonai is with you.’”
