The word 'Torah' means 'teachings'.
(Initial letters modidify the root in Hebrew, so 'mOReH' means 'teacher' and 'mesORaH' means 'tradition', etc.).
As a result of the language itself, 'Torah' means far more the the Five Books of Moses, or even the whole of the Jewish Bible, which is a strict hierarchy of three parts; Five Books of Moses, Prophets, and Writings.
Christians muddle this hierarchy, or turn it upside down, in order to justify their additions and modifications as well as interpretations.
I would not say a legit follower of Christ would do that, it was the opposition that wanted to cause stumbling blocks!
Every thing in your neck of woods is not hunky dory either there are a lot of references to missing Scripture in the OT as well as the NT!
The so-called lost books of the Bible are those documents that are mentioned in the Bible in such a way that it is evident they are considered authentic and valuable, but that are not found in the Bible today.
Sometimes called missing scripture, they consist of at least the following: book of the Wars of the Lord (Num. 21: 14); book of Jasher (Josh. 10: 13; 2 Sam. 1: 18); book of the acts of Solomon (1 Kgs. 11: 41); book of Samuel the seer (1 Chr. 29: 29); book of Gad the seer (1 Chr. 29: 29); book of Nathan the prophet (1 Chr. 29: 29; 2 Chr. 9: 29); prophecy of Ahijah (2 Chr. 9: 29); visions of Iddo the seer (2 Chr. 9: 29; 2 Chr. 12: 15; 2 Chr. 13: 22); book of Shemaiah (2 Chr. 12: 15); book of Jehu (2 Chr. 20: 34); sayings of the seers (2 Chr. 33: 19); an epistle of Paul to the Corinthians, earlier than our present 1 Corinthians (1 Cor. 5: 9); possibly an earlier epistle to the Ephesians (Eph. 3: 3); an epistle to the Church at Laodicea (Col. 4: 16); and some prophecies of Enoch, known to Jude (Jude 1: 14).
To these rather clear references to inspired writings other than our current Bible may be added another list that has allusions to writings that may or may not be contained within our present text, but may perhaps be known by a different title; for example, the book of the covenant (Ex. 24: 7), which may or may not be included in the current book of Exodus; the manner of the kingdom, written by Samuel (1 Sam. 10: 25); the rest of the acts of Uzziah written by Isaiah (2 Chr. 26: 22).
The foregoing items attest to the fact that our present Bible does not contain all of the word of the Lord that he gave to his people in former times, and remind us that the Bible, in its present form, is rather incomplete.
Matthew’s reference to a prophecy that Jesus would be a Nazarene (Matt. 2: 23) is interesting when it is considered that our present O.T. seems to have no statement as such. There is a possibility, however, that Matthew alluded to Isaiah 11: 1, which prophesies of the Messiah as a Branch from the root of Jesse, the father of David.
The Hebrew word for branch in this case is netzer, the source word of Nazarene and Nazareth. Additional references to the Branch as the Savior and Messiah are found in Jer. 23: 5; Jer. 33: 15; Zech. 3: 8; Zech. 6: 12; these use a synonymous Hebrew word for branch, tzemakh.
