Joshua 23:4
“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 Joshua called for all Israel, and for their elders, and for their heads, and for their judges, and for their officers, and said unto them, I am old and stricken in age:
And ye have seen all that the Lord your God hath done unto all these nations because of you; for the Lord your God is he that hath fought for you.
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;
