Joshua 23:7
“That 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:”
And the Lord your God, he shall expel them from before you, and drive them from out of your sight; and ye shall possess their land, as the Lord your God hath promised unto you.
Be 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;
That 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:
But cleave unto the Lord your God, as ye have done unto this day.
For 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.
