Joshua 23:8

6“Therefore be very courageous to keep and to do all that is written in the book of the law of Moses, that you not turn away from it to the right hand or to the left;

7that you not come 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 down yourselves to them;

8but hold fast to the LORD your God, as you have done to this day.

9“For the LORD has driven great and strong nations out from before you. But as for you, no man has stood before you to this day.

10One man of you shall chase a thousand; for it is the LORD your God who fights for you, as he spoke to you.
