@Nikud re: the forbidden chapter Isaiah 53, not much but a little bit of info here. Cool vid too.
Notice what he says about Daniel 9 as proof the Messiah would be cut off before the Second Temple destruction (70 AD) This directly disproves the Simon bar Kochba Messiah (90 AD -135 AD) appointed by Rabbi Akiva in connection with the Council of Jamnia and narrows the window down to the 90 year period of its reconstruction (20 BC - 70 AD)
Simon bar Kochba Messiah is one of six failed Messiahs that fringe groups beleived in, I have a thread here about them and the poor souls decived by them. Isaiah 53 is not forbidden it is taught just not that it's about the Messiah. They say the servant being mentioned in it is Israel, theyr'e wrong, but it's not a forbiden from being read.

An article written by the ones that made the video. In it they say that most Jews beleive it is forbidden. Good editing when the asked if they heard about this, inference to chapter 53 being forbidden to make it appear as if they were saying they never read Isaiah 53.
In reality less than 5% of the Prophets are read during the HaftTorah, but it is regularly read and discussed in bible study groups at synagogues and many of Rabbi have made their "careers" on it publishing multiple books of commentary. The Chumas I showed you, the blue book, has 20 different commentaries about it.
Difference in beleif, even a wrong beleif, isn't that same as it being forbidden.
So why don't most Jews recognize that Isaiah 53 is about Yeshua, it's because they've never read the 2nd testament. Why haven't they read it on their own if it's not read as part of the hafttorah? The same reasons why many "Christians" haven't read it. I appreciate the work that Jewish Voice, One for Israel, Jews for Jesus do when they are actually spreading the Message of Yeshua, the rhetoric they use to appeal to potential Christian donors hurts their cause more that the money they get helps. Plus is spreads disinformation that can bring out the worst in people.
This is what is taught about Isaiah 53 in the synagogues. It also has rebuttals against Christian beleifs which is good to know for those of us who actually share the Messiah with the House of Judah.

I'd like to state just because it's not read as the HattTorah doesn't mean it's not read and discussed in bible studies.
