Joshua 23:8 KJV

6Be ye therefore very courageous to keep and to do all that is written in the book of the law of Moses, that ye turn not aside therefrom to the right hand or to the left;

7That ye come not among these nations, these that remain among you; neither make mention of the name of their gods, nor cause to swear by them, neither serve them, nor bow yourselves unto them:

8But cleave unto the LORD your God, as ye have done unto this day.

9For the LORD hath driven out from before you great nations and strong: but as for you, no man hath been able to stand before you unto this day.

10One man of you shall chase a thousand: for the LORD your God, he it is that fighteth for you, as he hath promised you.
