Joshua 23:8-11

but cleave unto Jehovah your God, as ye have done unto this day. For Jehovah hath driven out from before you great nations and strong: but as for you, no man hath stood before you unto this day. One man of you shall chase a thousand; for Jehovah your God, he it is that fighteth for you, as he spake unto you. Take good heed therefore unto yourselves, that ye love Jehovah your God.
