Be strong and of good courage; for you shall cause this people to inherit the land which I swore to their fathers to give them.
1,2 SAMUEL, 1,2 KINGS, 1,2 CHRONICLES: In all these books, there are recorded frequent departures from the Pentateuchal Law of God by the kings of the people.  But Solomon's marriage with foreign women, contrary to the Law of Moses does not prove that the Law did not exist, but that Solomon wantonly violated it.  So with all the other violations.  Note the references to the tabernacle.  Where could the tabernacle have come from, if not from the Pentateuch?  The people complained and kicked against the sacrifices and offerings God had commanded, but why did they think they should make such offerings?  It was all taught in the Pentateuch, of course.  The Philistines took the ark, but why did Israel consider the ark sacred?  The answer is in the Pentateuch.  Saul visited the witch of Endor, but he disguised himself because it was illegal to do so.  What made it illegal?  The Pentateuchal teaching.  The tragic death of Abner  (2 Samuel 3ff) turned upon his failure to stay strictly within "the city of refuge," called Hebron.  Well, how did that tradition about "fleeing for refuge" to certain cities get started?  It is all outlined in the Pentateuch.  David rescued the ark of the covenant, but he ordered that it be carried on a new cart, instead of by hand, with fatal results to Uzziah.  Why was it wrong to haul the ark in a cart?  The Pentateuch records specific directions for carrying it "by hand."  Read all those glorying passages about building the Temple.  Where did the design of it come from?  The whole thing was a larger and more elaborate replica of the ancient tabernacle, all of the instructions for which are in the Pentateuch.  Solomon offered thousands of sacrifices.  Why?  Such sacrifices were authorized for Israel only in the Pentateuch.  Solomon's apostasy is recorded (1 Kings 11).  Apostasy from what?  The Law of Moses as revealed in the Pentateuch.
