On a side note, i watch and step in as i can when missionaries hunt the deform. They say "you know Isaiah 51/53/whatever is the forbidden chapter? Your Rabbi doesnt want hou to know it", and Orthodox Jews, after a vert boisterous laugh, and extremely confused why it is so effective on the deform. Every chapter and pasuk in Torah is the forbbiden chapter by them, so thats why theyre so easy. The only missionaries the deform know how to respond to is kiruv Rabbis.
