Joshua 23:6-8

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

7 That you 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 to them:

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