Here we are already in the fifth book of the Torah.  Devarim/Deuteronomy is a little different than the first four books as its words were not quoted directly from YHWH, but came through the man, "Moshe":
Devarim/Deuteronomy 1:1 These are the words Moshe spoke to all Israel in the desert east of the Jordan...

But lest we think all of Moshe's words could not be traced back to the Almighty:

Devarim/Deuteronomy 1:3 ...Moshe spoke to the children of Israel according to all that YHWH  had given him as commandments to them...

Quoting from the rabbi at Beit Hasha'ar:

But since these words were not directly dictated by HaShem, the foundation for the words in Moshe's fifth book is already laid in the first four books.  Remember that the foundation of a house supports the whole house.  In the same way, the first four books of the Torah were dictated to the prophet Moshe, letter by letter, and written down with precision.  Thus they became the foundation for the fifth book of Moshe.  These five books, that are called the Torah of Moshe, are in turn, the foundation for the rest of the Scriptures.  The prophetic books that were later added, beginning with Yehoshua (Joshua), don't change anything in the foundation, as written:

Devarim/Deuteronomy 4:2 "You shall not add to the word which I command you, nor take from it, that you may keep the commandments of YHWH your Elohim which I command you.
Devarim/Deuteronomy 12:32 "Whatever I command you, be careful to observe it; you shall not add to it nor take away from it.

                     

Every book of the Bible that is after the Torah...all the way to the end of Revelation then, can neither add to nor take away anything from the words of the Torah that YHWH gave to the Israelites on Mt. Sinai.  The Torah is the foundation of the house that supports the whole structure.  All other books, although inspired, can only give more explanation and revelation to what has already been laid as the foundation.  Believing in the written Torah, means you believe in the Living Torah.  They are exactly of the same essence of truth.

John 5:46 "For if you believed Moshe, you would believe Me; for he wrote about Me.

"Nothing new, except for more light" was also Rav Sha'ul's testimony:

Acts 26:22 'Having obtained, therefore, help from Adonai, till this day, I have stood witnessing both to small and to great, saying nothing besides the things that both the prophets and Moshe spoke of as about to come, 23 that the Messiah is to suffer, that He would be the first to rise from the dead, and would proclaim light to the people and to the nations.

Let's take a look at one of the opening verses in our parasha:

Devarim/Deuteronomy 1:5 On this side of the Jordan in the land of Moab, Moshe began to explain (ba'ar) this Torah, saying...

The Hebrew word translated as "explain" is ba'ar.  It means "to explain or to make clear."  Moshe is presenting another way to look at the Torah.  In fact, Moshe is attempting to take his listeners to the heart of the Torah through explanations, applications, and comments about what has already been written in the first four books.   Is this also not what Yeshua did?  Did He not also point people to the heart of the Torah?  Yeshua quoted Devarim more than any other book of the Torah.  Following is an obvious connection.  The context is after Yeshua's resurrection.  Two men are walking along the road to Emmaus and Yeshua approaches them, though they do not recognize Him.  They have confusion because they have not had their eyes opened to the Hebrew Scriptures.  Yeshua gives them revelation in order to "know Him."

Luke 24:27 And beginning at Moshe and all the Prophets, He expounded to them in all the Scriptures the things concerning Himself. 28 Then they drew near to the village where they were going, and He indicated that He would have gone farther. 29 But they constrained Him, saying, "Abide with us, for it is toward evening, and the day is far spent." And He went in to stay with them. 30 Now it came to pass, as He sat at the table with them, that He took bread, blessed and broke it, and gave it to them. 31 Then their eyes were opened and they knew Him; and He vanished from their sight. 32 And they said to one another, "Did not our heart burn within us while He talked with us on the road, and while He opened the Scriptures to us?" 33 So they rose up that very hour and returned to Jerusalem, and found the eleven and those who were with them gathered together, 34 saying, Adonai is risen indeed, and has appeared to Simon!" 35 And they told about the things that had happened on the road, and how He was known to them in the breaking of bread. 36 Now as they said these things, Yeshua Himself stood in the midst of them, and said to them, "Peace to you." 37 But they were terrified and frightened, and supposed they had seen a spirit. 38 And He said to them, "Why are you troubled? And why do doubts arise in your hearts? 39 "Behold My hands and My feet, that it is I Myself. Handle Me and see, for a spirit does not have flesh and bones as you see I have." 40 When He had said this, He showed them His hands and His feet. 41 But while they still did not believe for joy, and marveled, He said to them, "Have you any food here?" 42 So they gave Him a piece of a broiled fish and some honeycomb. 43 And He took it and ate in their presence. 44 Then He said to them, "These are the words which I spoke to you while I was still with you, that all things must be fulfilled which were written in the Torah of Moshe and the Prophets and the Psalms concerning Me." 45 And He opened their understanding, that they might comprehend the Scriptures.
I want to focus on the words in Luke 24:44 - "these are the words." Yeshua goes on to "open their understanding" to "comprehend the Scriptures."  That is, He will "explainba'ar the "Torah of Moshe and the Prophets and the Psalms." He will take them straight to the heart of truth through "these words." In fact, "these are the words" is the same phrase Moshe uses as he attempts to open the understanding of the Israelites!  Moshe explained the Torah to the Israelites just as Yeshua did on the road to Emmaus:
Devarim/Deuteronomy 1:1 These are the words which Moshe spoke to all Israel on this side of the Jordan in the wilderness
If we go back to Luke 24:44, the Greek word for "fulfilled" is pleroo which means "to fill up to the full or to make complete with life."  This was the goal of Yeshua in His first coming.  He made the Torah and the Prophets "full of life" as He expounded on the promises and the will of  YHWH.  The same Greek word is found in a more familiar verse:
Matthew 5:17 " Do not think that I came to destroy the Torah or the Prophets. I did not come to destroy but to fulfill (pleroo). 18 "For assuredly, I say to you, till heaven and earth pass away, one jot or one tittle will by no means pass from the Torah till all is fulfilled.
So what does Yeshua mean when he speaks of a "new commandment"?  Isn't He "adding to the Torah"?
John 13:34 "A new commandment I give to you, that you love one another; as I have loved you, that you also love one another.
If we consider what we have learned, it is not an extra (614th) commandment, but a commandment that has been given "new revelation."  Yeshua sought to re-instill, to reinvigorate the true intent of YHWH 's Torah within Israel.  A commandment renewed and given new life.  He touched on the heart of the commandment with greater clarity, just as the disciple Yochanan (John) alluded to:
1 John 2:7 Brethren, I write no new commandment to you, but an old commandment which you have had from the beginning. The old commandment is the word which you heard from the beginning. 8 Again, a new commandment I write to you, which thing is true in Him and in you, because the darkness is passing away, and the true light is already shining.

Rav Sha'ul (Paul) spoke of the "mystery of Messiah" which was newly revealed to the believers in the first century.  He also spoke of the "stewardship" he had been given from Elohim for "new revelation" to the saints.  This was all for the purpose of "fulfilling" (pleroo) the word of YHWH. 

Colossians 1:25 of which I became a minister according to the stewardship from Yah which was given to me for you, to fulfill (pleroo) the word of Yah, 26 the mystery which has been hidden from ages and from generations, but now has been revealed to His saints. 27 To them Yah willed to make known what are the riches of the glory of this mystery among the nations: which is Messiah in you, the hope of glory.
Ephesians 3:3 how that by revelation He made known to me the mystery (as I have briefly written already,  by which, when you read, you may understand my knowledge in the mystery of Messiah), 5 which in other ages was not made known to the sons of men, as it has now been revealed by the Spirit to His holy apostles and prophets: 6 that the nations should be fellow heirs, of the same body, and partakers of His promise in Messiah through the good news.
Something "newly revealed" does not mean that the truth was not found in the Torah, but it means that it was not yet revealed, it was still hidden, or a "mystery."  I will end with another quote from the rabbi at Beit Hasha'ar:
"The Torah can be compared to a dark room that holds many pieces of furniture.  It is impossible to see what is in the room if one does not light a lamp.  The more light there is, the more details are revealed in the room.  Revelation is like that lamp.  The same thing happens when one develops film from an old camera.  Before it is developed one cannot see the pictures that have been there since they were taken.  It is the same way with the counsel of the Eternal; it is hidden in the Torah of Moshe, and later revelations have only brought into the light that which was there already.  These revelations can only be given through the Spirit of the Eternal."
The five books of the Torah have the highest level of authority among all of the inspired Scriptures.  Nothing can be added to or taken away from these truths.  We do need further revelation in the future in order to take us into His promises.   This will most certainly come because all of His promises are "yes and amen!"
2 Corinthians 1:20 For all the promises of Yah in Him are Yes, and in Him Amen, to the glory of Yah through us.
Now something to share with you.  Joshua and Caleb Waller from HaYovel have put out another video.  This one will take you to the community of Itamar in Samaria to meet Baruch and Batya Erdstein.  Batya fashions stunning handcrafted ceramic dishes and decoration that each incorporate the unparalleled beauty, ancient history and miraculous story of the Land of Israel.
