II Chronicles 20:15-17

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.”
