Joshua 23:5

And the Lord your God he shall expel them from before you
That is, such of them as yet remained among them:

and drive them from out of your sight;
the same thing expressed by different words, for the confirmation of it:

and ye shall possess their land, as the Lord your God hath promised
unto you;
all which is to be understood on condition of their good behaviour towards the Lord, and obedience to his commands; by which tenure they held the possession of the land when put into it, and for their disobedience did not possess the whole.
