2 Chronicles 20:15, 17

He said, “Listen to me, King Jehoshaphat and all you people living in Judah and Jerusalem. The LORD says this to you: ‘Don’t be afraid or discouraged because of this large army. The battle is not your battle, it is God’s.

You won’t need to fight in this battle. Just stand strong in your places, and you will see the LORD save you. Judah and Jerusalem, don’t be afraid or discouraged, because the LORD is with you. So go out against those people tomorrow.’ ”
