2 Chronicles 20:16-17

16To morrow go ye down against them: behold, they come up by the cliff of Ziz; and ye shall find them at the end of the brook, before the wilderness of Jeruel.12

17Ye shall not need to fight in this battle: set yourselves, stand ye still, and see the salvation of the Lord with you, O Judah and Jerusalem: fear not, nor be dismayed; to morrow go out against them: for the Lord will be with you.
