Yesterday's mishnah raised the case of heirs bringing a sacrifice on behalf of someone who died before being able to offer it - and whether they would do the laying on of hands. Here, we are privy to a contradiction in the materials over whether they do it. Plus, another mishnah, with the list of all those who can, under the right circumstances, do the laying on of hands (semichah). Also, more on the semichah - specifically, how it was done with 2 hands, and how we know that it is supposed to be done with 2 hands. Plus, Resh Lakish's stance on this halakhah and the way he argues for and against it, with some frustration.
