The Masoretic (official) text of the Hebrew Old Testament was assembled centuries after the documents were first written. Textual criticism is not only allowable, it’s an imperative.
The "Massoretic text" refers to the fully pointed text with vowels, cantation, punctuation, etc. The actual original text of the Torah has never been changed since the day it was written down by Moses. It consists of consonants only and may be found in the ark of every Orthodox synagogue in the world, each copy having been made from a copy that existed before it.
This need to declare the Hebrew Bible a fraud is something atheists, moslems, and many chr*stians seem to share in common. Unsurprising, since their worldviews depend on it being a fake.
The fact that ZC will not even write the name of Christ should tell you much.
