2 Chronicles 20:14-17

14In the middle of the congregation, the Spirit of the Lord came on Jahaziel (son of Zechariah, son of Benaiah, son of Jeiel, son of Mattaniah, a Levite from Asaph’s descendants),

15and he said, “Listen carefully, all Judah and you inhabitants of Jerusalem, and King Jehoshaphat. This is what the Lord says: ‘Do not be afraid or discouraged because of this vast number, for the battle is not yours, but God’s.

16Tomorrow, go down against them. You will see them coming up the Ascent of Ziz, and you will find them at the end of the valley facing the Wilderness of Jeruel.

17You do not have to fight this battle. Position yourselves, stand still, and see the salvation of the Lord. He is with you, Judah and Jerusalem. Do not be afraid or discouraged. Tomorrow, go out to face them, for the Lord is with you.’”
