Well, I believe all scripture is God breathed or inspired by God. And yes Jesus did not specifically state that he nailed them to the cross, but in the other passages I wrote to you he means that is what will take place once he fulfills the prophecies and the law. The Law given to Moses and the Jews excluded all other nations, however God made a promise to Abraham that all nations (Jews and Gentiles) would be blessed. This promise was fulfilled through Abraham's seed, and that Seed is Jesus. Because of sin the Law of Moses was added until Christ the seed should come. Then he would give us a more perfect law to follow. The bible says in Rom. 7:4 that we become dead to the law through the body of Jesus Christ because the law was nailed to the cross and the new testament or will takes it's place. The principles of the commandments are in the NT but they were perfected. So yes you are right, Jesus did not say he came to nail the old law to the cross, but the promise has been fulfilled. Paul as a writer for the bible received inspiration from God as to what to write. Thus Jesus came to nail the old law to the cross.
In the following verses we have the Word of Jesus by the Apostles and prophets of Jesus Christ
>>>The Word is sent from the Father through the Son.
John 12:48-50 48 He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day. 49 For I have not spoken of myself; but the Father which sent me, he gave me a commandment, what I should say, and what I should speak. 50 And I know that his commandment is life everlasting: whatsoever I speak therefore, even as the Father said unto me, so I speak.
>>>The Son gave the Word to the Apostles
John 14:26 26 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
John 15:26-27 26 But when the Comforter is come, whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, he shall testify of me: 27 And ye also shall bear witness, because ye have been with me from the beginning.
John 15:26 - 16:1 26 But when the Comforter is come, whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, he shall testify of me: 27 And ye also shall bear witness, because ye have been with me from the beginning.
>>> The Father gave the Word to the Son was throught the Holy Spirit to the Apostles.

The word given to the apostles.
John 17:6 6 I have manifested thy name unto the men which thou gavest me out of the world: thine they were, and thou gavest them me; and they have kept thy word.
John 17:9 9 I pray for them: I pray not for the world, but for them which thou hast given me; for they are thine.
John 17:14 14 I have given them thy word; and the world hath hated them, because they are not of the world, even as I am not of the world.
John 17:17 17 Sanctify them through thy truth: thy word is truth.
The written Word given to us through the Apostles
John 17:20-23 20 Neither pray I for these alone, but for them also which shall believe on me through their word; 21 That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me. 22 And the glory which thou gavest me I have given them; that they may be one, even as we are one: 23 I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.
I think we're in agreement that interpretation is not the same as the actual words of the Scriptures.
If not ... well, that happens :-).
