Joshua 23:6 (KJV)

Behold, I have divided unto you by lot these nations that remain, to be an inheritance for your tribes, from Jordan, with all the nations that I have cut off, even unto the great sea westward.

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.
