Today, the Gemara asks: Why do I need all of these? No, the Gemara is not downsizing and looking to rid itself of sweaters that it hasn’t worn in three years. Rather, it’s asking about a mishnah that teaches that s’chach (roofing materials) that would normally render a sukkah invalid are fine if they are located at the outer edge of the […]

Those of us who are into interior design hang all sorts of things in our living spaces to personalize them. We hang pictures on our walls. We hang curtains in our windows. We hang plants in our windows and on our patios. Today’s daf asks about hanging something else — the wall itself! Most of […]

Building a sukkah from scratch is a great deal of work. What if you could use something you already have — like your house?

While the core of the community traces its ancestry to the Iberian peninsula, and the Jewish exodus that began in the late 15th century, Jamaican Jews today come from Poland, France, Italy, Africa, Israel, Turkey, and […]

In the Gemara today, we are deep into a discussion of appropriate s’chach (roofing material) for the sukkah. We learned in a mishnah that bundled materials are inappropriate, as the branches should be loose and scattered (though the Gemara accepts “naturally” bundled material, so you don’t have to physically rip palm branches apart). Plants that smell bad or that are […]

One of the challenges that face those studying the rabbinic mindset is to understand how difficult it is to translate accurately from one language to another and do justice to the concepts.  Nowhere is this more obvious than in discussing issues of tum’ah and taharah, which are usually translated as “impurity” and “purity.” In English, for example, these […]

Jewish doctors warned against conspiracy theories claiming the COVID-19 vaccine causes infertility or contains products derived from pork.
