Bava Batra 116: Student Heirs
More on inheritance - with a harsh pronouncement: a man who dies without sons is reflecting God's wrath. Plus, the story of R. Yochanan, who focused on the inheritance in students, because he himself had lost 10 sons. As well as R. Yehoshua ben Levi's special effort to pay a shiva visit/ condolence call to those who died without sons. Also, the hierarchy or priority of heirs, and how that is passed on to the next heirs as well.
