Not Adding (בל תוסיף)

In Deuteronomy it teaches לא תוסיפו מן הדבר אשר אלקים מצוה אותך ולא תגרעו ממנו “You shall not add or subtract to the law which I command you today.”[1] The example given by the Code of Jewish Law for not adding is not adding a 5th species to one’s lulav.[2] Instead, we need to follow the exact 4 species that are outlined in the Torah. 

A fun example of this was a drawing which had species native to Canada (where the artist lived) rather than the 4 from Israel. It included a maple leaf for lulav. I shared it and received the following reply from one of my teachers: “nice idea for someone else’s religion.” We are fortunate in California that we can grow all 4 species here as our climate is close enough to Israel’s. Imagine growing up in Milwaukee like me where none of these species naturally grow. I understood the desire to get native species while concurrently maintaining our tradition.

Many think “does Judaism really not add or subtract?” At times it feels like we have added many prohibitions over the centuries while refusing to subtract any. A core reason I am a Conservative Jew is Rabbi Mordecai Waxman’s twin pillars of tradition and change-that we can maintain traditions while living in ever evolving situations with new areas of knowledge that Jewish law has to confront. Upon entering rabbinical school, I read a book that said Conservative Judaism is the most faithful denomination to the tradition of not adding or subtracting. 

Regardless as to whether or not that is correct-at times I have my doubts-I hope we will take the tradition of not adding and subtracting seriously. At times Jewish leaders have added so many fences around prohibitions that the original prohibition becomes lost in the shuffle. At other times, we adopt the attitude “anything goes” and throw off traditions that are there for a reason. My hope is that on the Conservative Movement we can continue to maintain the solid middle ground-not adding to the burdens but neither subtracting from our responsibilities as members of the tribe.

Why No Lulav and Etrog on Shabbat

Something really bothers me about when Rosh Hashanah and Sukkot begin on Shabbat. That is that we do not blow shofar or wave lulav and etrog on Shabbat. Why is this the case? Because someone might carry these items outside of an eruv, thereby violating Shabbat. This begs the question why not build an eruv so this is a non-issue? Rabbi Yohanan ben Zakkai issued a takanahלא פלוג, that we should not divide ourselves from other communities.[1] Hence no one blows shofar or waves lulav and etrog on Shabbat.One way of looking at this is the absurdity of following archaic traditions. More people are in shul on Shabbat-therefore we should do these rituals davka (specifically) on Shabbat. The other belief is the importance of tradition-just like two days of yom tov is a tradition that must be maintained, so too should the custom of not waving the lulav and etrog on Sukkot on Shabbat. You don’t like it? Come back tomorrow or during one of the other days of Sukkot!

There is one caveat that I will make. Following לא פלוג presumes a unity between communities that I’m not sure can be assumed today. There are those who feel that we are illegitimate for being Conservative Jews, and those feelings are unlikely to change. There remains a tendency to look over our right shoulders to see what our more traditional brethren are doing. Case in point: I became close to applying to the recently formed, modern orthodox rabbinical school Yeshivat Chovevei Todah, feeling that if I received smicha from there all of world Jewry would accept me as a rabbi. How wrong I was. 

I do feel that customs can evolve and change. With that being said, I recognize the importance of “kishke issues,” those things we feel in our gut are right and no amount of rationalisation will change. The truth is the tradition not to wave lulav and etrog on Shabbat is well-established. My one disappointment in maintaining it, which we will continue to do, is it means that some will not get to see the lulav and etrog waived this year. Please come back tomorrow to take part in this ritual.
