Over time, the manuscripts fell into disrepair, because they were not republished, as today's publications, but were copied by hand.
The rewritten manuscript of the New Testament texts was a kind of reprint. You know how they write - updated and updated.
The fact is that in those years the canon of the New Testament was being formed, for example the message to the Hebrews was under a big question because of the lack of authorship. Other manuscripts were preserved, some of them became part of the Bible of some faiths.
That is, everything was not as definite and unambiguous as it is today. The copyists of the Old Testament were and to this day are special people. They have their own order, the principle of operation, which avoids the majority of errors. The copyists of the New Testament often had monks punished for their misdeeds. So, at the moment we have reached a large number of copies of the Scriptures and passages of the New Testament Scriptures. They can be very different from each other.
On the basis of these copies, a number of texts have been created (the three main ones are listed below), which may differ greatly from one another. These (the following) texts became the basis for translating the Bible into other languages.
TR - Textus Receptus1516. The first New Testament in Ancient Greek was published by the Dutch scientist Erasmus of Rotterdam.
Based on existing and available at that time manuscripts, because it was of low quality and contained many errors.
This was the first pancake.
Textus Receptus served as the basis for the translation of a number of authoritative editions of the Bible: Lutherbibel, Tyndale Bible, King James Version ...
WH - Westcott and Hort textNew York 1881. Version of the text of the New Testament in the ancient Greek language of Professors Cambridge Brook Foss Westcott and Fenton John Anthony Hort.
