Mo'ed Katan 26
When is one required to rend their garment? \u2022 After his ascension, was Eliyahu HaNavi's rebbetzin permitted to remarry? \u2022 Were the eighty men on their way to Jerusalem after Gedalia was assassinated permitted to gash their flesh? \u2022 Was Rabbi Akiva permitted to strike himself until he bled after Rabbi Eliezer died? \u2022 Is one required to inform a would-be mourner of his loss?
