text: ok-for those out there that think people ask stupid religious questions--how did the prophet isaiah die ?   both jewish and christian traditions state that he was killed by being sawed in half. some interpreters believe that this is what is referred to by hebrews 11:37 (in the new testament), which states that some prophets were "sawn in two". it is also mentioned in the book of the martyrdom of isaiah that he lived into the days of manasseh, and was also sawn in half with a wooden saw.
