This book of the law shall not depart out of your mouth, but you shall meditate thereon day and night, that you may observe to do according to all that is written therein: for then you shall make your way prosperous, and then you shall have good success.
JUDGES: Like every other book in the Bible, the shadow and teaching of the Pentateuch lie over every word of it.  Look at  Judges 1:27-34, where it is recounted how various tribes of Israel did not "drive out the inhabitants of the land."  But, indeed why were they expected to drive them out?  It is in the teachings of the Pentateuch that they were commanded to drive them out.
