Matthew Poole and continuators on Joshua 23:6

6 Be ye therefore very couragious , 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 .

For it will require great Courage and Resolution to execute all the Commands of Moses, and particularly, that of expelling and destroying the residue of the Canaanites.

i. e. In one kind or other, by adding to the Law, or diminishing from it, as Moses speaks.
