It might seem like a minor detail, but when we delve into the texts, we uncover some fascinating layers of meaning.

Our journey begins with a verse from Shemot (Exodus) 13:9, talking about the tefillin, those small leather boxes containing scrolls of parchment inscribed with verses from the Torah, bound to the arm and head during weekday morning prayers. The verse mentions placing the tefillin "upon your hand." But which hand?

The Sifrei Devarim, a collection of legal interpretations on the Book of Deuteronomy, takes a surprising stance. It argues that "hand," when mentioned without further specification, actually refers to the left hand! How do they arrive at this conclusion? By looking at other instances in the Bible where hands are mentioned.

Consider Isaiah 48:13: "My hand also has founded the earth, and My right hand has spanned the heavens." Or Judges 5:26: "She sent forth her hand for the (tent-) peg and her right hand for the laborers' hammer." And even Psalms 74:11: "Why do You withdraw Your hand, and Your right hand, etc." In each case, the "right hand" is explicitly identified, suggesting that when "hand" appears alone, it implicitly means the left. Pretty clever. But hold on, the discussion doesn't end there! Rabbi Nathan offers a different perspective, focusing on the act of writing itself. He draws a parallel between the commandment "And you shall bind them… and you shall write them" (Deuteronomy 6:6-7). Since writing is typically done with the right hand, Rabbi Nathan argues that binding – in this case, the binding of the tefillin – should also be associated with the right. And if binding is with the right, then the place where it's bound – the arm – must be the left!

So, what’s the big deal? Why this focus on left versus. Well, in many cultures, including ancient Jewish society, the right hand is often associated with strength, skill, and blessing. It’s the dominant hand for most people, the one we use for important tasks. The left hand, in contrast, is sometimes seen as weaker or less significant.

However, the Sifrei Devarim and Rabbi Nathan's interpretation challenge this simplistic view. By associating the left hand with sacred practices like wearing tefillin, they elevate its status, imbuing it with holiness. It's a reminder that even the seemingly less dominant aspects of ourselves, or of the world, can be vessels for the divine. : we often focus on our strengths, on what we do well. But what about our weaknesses, our vulnerabilities? Perhaps those are the very places where we can connect with something greater than ourselves. Maybe it's in acknowledging our limitations that we open ourselves up to receive blessings and find deeper meaning.

So, the next time you put on tefillin – or simply go about your day – consider the significance of both your right and left hands. Both have a role to play, both contribute to the tapestry of our lives. And who knows, maybe the "weaker" hand holds a hidden strength, waiting to be discovered.
