Study Guide Shabbat 133

Why do we need a drasha to teach us that brit milah overrides the prohibition to cut a leprous mark – isn’t it an act that one does without intention and one should be exempt? From where do we derive that brit milah done not on the eighth day does not override Yom Tov (and obviously, Shabbat). Four answers are brought. Rav Yehuda paskens in the name of Rav like Rabbi Akiva that preparations for milah do not override Shabbat. He also holds like Rabbi Akiva regarding the same issue with the Pashal sacrifice. Why does he need to say this in both cases – wouldn’t it be obvious we can learn from one to the other? All things relating directly to the brit milah override Shabbat – the mishna states what that includes. The gemara says it even includes pieces of the skin that are left that are necessary as part of the mitzvah to remove. However, if they do not prevent the mitzvah from being fulfilled, one can only remove them if one is still in the process of cutting but once the mohel has stopped, he cannot cut those pieces. The gemara tries to connect this opinion with a tanna who in a different case who holds that once one stops, the action is no longer connected with the previous one. Three different tannaitic arguments are brought – the first two are rejected. Why is metzitza allowed? The gemara discusses bandages as mentioned in the mishna and Rava taught how to make a good bandage and as a result got some people upset as he “stole” their business as they knew how to do this and would sell to others. Rava tries to appease them.
