What verses in ben Sira are we permitted to learn? Can one sing verses from Shir HaShirim in a tune other than the taamei hamikra? What about from other books? What is “someone who uses incantations” that according to the mishna will not get a part in the world to come? Are there ways to do this that are permitted? Is calling to demons allowed? Some stories are told about the rabbis visiting Rabbi Eliezer ben Hurkanus while he was sick and the conversations that took place relating to suffering. Yeravam is mentioned in the mishna as one who has no portion in the world to come. What did he do wrong? What is the meaning of his name?
