Sanhedrin 101 - March 28, 28 Adar

Can one sing verses from Shir HaShirim in a tune other than the taamei hamikra? In what manner/context is it problematic to read verses from the Torah? What is "someone who uses incantations" that 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 their conversations about suffering. Yeravam is listed in the Mishna as one who did not receive a portion in the World-to-come. What is the meaning of his name? Why did he lose his share in the World-to-come? What caused him to sin?
