2 Chronicles 20:15-17

Thus saith the Lord, Be not afraid You have admitted fear enough to induce you to have recourse to God: now do not give way to that fear which would drive you from him. The battle is not yours It is not in your own cause, nor in your own strength, that you engage; the battle is God's And he doth and will interest himself in your favour, as you have desired, and will fight for you. To-morrow go ye down From Jerusalem, where he and his army now were, which stood upon high ground. Ye shall not need to fight in this battle The work shall be done to your hands, and you will not need to strike a stroke, nor shall you be the instruments, but only the spectators of the defeat of the enemy. O Judah and Jerusalem, fear not Thus does he encourage them to trust in God, though the danger was very threatening, and to expect certain victory and deliverance.
