In the above mentioned article which I provided a link to, Tabor says the following.
'One thing I had noticed in my own work on the book of Revelation over the years was that the explicit references to either “Jesus” “Christ,” or “Jesus Christ” outside the letters to the churches of chapters 2 & 3, are mostly clustered in chapters 1 and 22, with few in the middle chapters.
But what is even more astounding, to me at least, was the observation that nearly all of these references can be easily removed without detracting in any way from the structure or flow of the passages in which they occur. In other words, one could get the distinct impression that references to Jesus Christ lay quite lightly on the text and could even be seen as secondary interpolations.
In the references below I have put these interpolative elements bold italicized brackets. This exercise strongly suggests that these are later additions to an original Jewish text inserted to “Christianize” a book that in its origins had nothing to do with Jesus. This is a rather astounding phenomenon and once one sees it it seems clear that the underlying original text remains intact and makes complete sense without these references:'
In the article Tabor also says the following. 'In contrast to these references to Jesus, that so clearly exhibit a heavy hand of Christian interpolation, one finds multiple references to the LORD (Yahweh/Yehovah) God Almighty, as well as “his Messiah,” that echoes closely the language of the prophetic texts of the Hebrew Bible. None of these contain explicit references to Jesus and clearly exhibit a textual integrity that reflects the language and thought world of pre-Christian thoroughly Jewish apocalypticism:'
