2 Chronicles 20:15

and he said, “Listen, all Judah, and you inhabitants of Jerusalem, and you, King Jehoshaphat. Yahweh says to you, ‘Don’t be afraid, and don’t be dismayed because of this great multitude; for the battle is not yours, but God’s.

And he said, Hearken ye, all Judah, and ye inhabitants of Jerusalem, and thou king Jehoshaphat, Thus saith the LORD unto you, Be not afraid nor dismayed by reason of this great multitude; for the battle is not yours, but God’s.
