2 Chronicles 20:14-17

14the Spirit of the Lord came upon one of the men standing there. His name was Jahaziel son of Zechariah, son of Benaiah, son of Jeiel, son of Mattaniah, a Levite who was a descendant of Asaph.

15He said, “Listen, all you people of Judah and Jerusalem! Listen, King Jehoshaphat! This is what the Lord says: Do not be afraid! Don’t be discouraged by this mighty army, for the battle is not yours, but God’s.

16Tomorrow, march out against them. You will find them coming up through the ascent of Ziz at the end of the valley that opens into the wilderness of Jeruel.

17But you will not even need to fight. Take your positions; then stand still and watch the Lord’s victory. He is with you, O people of Judah and Jerusalem. Do not be afraid or discouraged. Go out against them tomorrow, for the Lord is with you!”
