II Chronicles 20:12-17

O our God, will You not judge them? For we have no power against this great multitude that is coming against us; nor do we know what to do, but our eyes are upon You.” Now all Judah, with their little ones, their wives, and their children, stood before the LORD. Then the Spirit of the LORD came upon Jahaziel the son of Zechariah, the son of Benaiah, the son of Jeiel, the son of Mattaniah, a Levite of the sons of Asaph, in the midst of the assembly. And he said, “Listen, all you of Judah and you inhabitants of Jerusalem, and you, King Jehoshaphat! Thus says the LORD to you: ‘Do not be afraid nor dismayed because of this great multitude, for the battle is not yours, but God’s. Tomorrow go down against them. They will surely come up by the Ascent of Ziz, and you will find them at the end of the brook before the Wilderness of Jeruel. You will not need to fight in this battle. Position yourselves, stand still and see the salvation of the LORD, who is with you, O Judah and Jerusalem!’ Do not fear or be dismayed; tomorrow go out against them, for the LORD is with you.”
