You know how sometimes during a conversation you start to zoom out because the topic fails to grab your attention? That’s kind of what this week’s parshios, Tazria and Metzora, do. They begin a lengthy discussion about laws of spiritual impurity before going on to cover the incredibly exciting topic of tzara’as (skin disease), the metzor (the one suffering it), and their laws of purification. Can’t wait, huh? But, before we go there, the Torah reminds us about the need to perform a Bris on an eight-day old male which, quite frankly, seems out of place. True, the parsha starts off talking about birth, but there are other more relevant places for the mitzvah of Bris, which is why commentators try to learn something from it.
