He said, "Listen, all Judah and the inhabitants of Jerusalem and King Jehoshaphat: thus says the LORD to you, 'Do not fear or be dismayed because of this great multitude, for the battle is not yours but God's. ... You [need] not fight in this [battle;] station yourselves, stand and see the salvation of the LORD on your behalf, O Judah and Jerusalem.' Do not fear or be dismayed; tomorrow go out to face them, for the LORD is with you."
