Rarely does the synagogue calendar align with such poetic precision. This past Shabbat, our congregation witnessed a Brit Milah (circumcision) during the morning service—a ceremony many of us realized we hadn’t seen performed on the Sabbath in years.

The event served as a living bridge between the physical and the spiritual, made even more resonant by the week’s Torah portion: Parshat Shemini. In Hebrew, Shemini literally means “eighth,” and it offers a profound numerical blueprint for the very purpose of a Jewish life.

The Geometry of Existence: 6, 7, and 8

During the service, Rabbi Ari Soussan delivered a compelling breakdown of the “metaphysical mathematics” that govern our world. To understand why a Brit Milah must occur on the eighth day, one must first look at the numbers that lead up to it:

The Number Six (The Physical): This number embodies the material dimension. Just as a three-dimensional cube has six faces—top, bottom, right side, left side, front, and back—the six days of creation represent the tangible, finite world we inhabit.

The Number Seven (The Spiritual or Metaphysical): This numeral signifies the infusion of the soul into creation. Shabbat, the seventh day, marks the cessation of labor—a sacred sanctuary in time that draws us toward prayer, Torah study, family bonds, and communal fellowship.

The Number Eight (The Synthesis): While seven represents transcendence beyond the mundane, eight embodies the profound act of integrating spirituality into the physical world—elevating the material to holiness through covenant and service.

By performing brit milah—a profound physical act upon the human body—on the eighth day, we transcend mere spirituality. We sanctify the material itself, forging the eternal union where the transcendent divine meets the tangible human form.

The ‘Eighth Day’ in Action: From the Tabernacle to Today

This pattern of an “eighth-day” synthesis—where the material world is rededicated to a higher, spiritual purpose—is the heartbeat of Jewish history. From my perspective, we see this transition from the physical “seven” to the sanctified “eight” in three pivotal examples:

The Tabernacle (The Biblical): Parshat Shemini marks the climax of the Tabernacle’s inauguration. After seven days of preparation and anointing, the eighth day arrived. It was the moment the priests transitioned from “preparing” to “ministering,” and the Divine Presence finally resided within a physical structure on earth.

Chanukah (The Historical): We celebrate how a small jar of physical oil miraculously lasted for eight days. This wasn’t merely a miracle of fuel; it allowed for the rededication of the physical Temple, turning a defiled space back into a sanctuary for G-d.

October 8 (The Modern): Following the brutal physical devastation of October 7, the nation of Israel arose on the morning of the 8th. We took the physical agony of 1,200 martyrs and channeled it into a resolute, unified spiritual strength. In that “eighth-day” response, a shattered people found a path to rectification, transforming grief into a massive wave of national unity and a renewed connection to the Divine.

Elevating the Mundane

This concept is the “secret sauce” of Judaism. We take our raw, instinctive drives—our animalistic side—and instead of suppressing them, we refine them through the lens of mitzvot (commandments). We prove that holiness is not found by escaping the world but by engaging with it properly:

Eating becomes holy through blessings (Brachot) that acknowledge the source of our sustenance.

Physical intimacy is elevated through the laws of family purity (Taharat HaMishpacha), turning instinct into a sacred bond.

Commerce is transformed into a spiritual act through the requirement for honesty. By adhering to the mitzvah of ethical integrity and “just scales,” we turn the pursuit of a livelihood into an ongoing act of Divine service.

The Lesson in the Cry

There was a moment during the ceremony that made this abstract philosophy feel viscerally real. I looked around the room and saw that I wasn’t the only one who was moved when the baby started to cry during the circumcision. Others were crying along with him, visibly feeling his pain and empathizing with his first trial in this world.

This collective empathy is the ultimate bridge between the physical and the metaphysical. It is not enough to simply witness others’ challenges; the “eighth-day” mindset requires us to incorporate that shared pain into our own determination. We take the sting of physical experience and transmute it into a drive for compassion. We use that empathy as fuel to learn, to grow, and to engage in Tikkun Olam—the active repair of the world.

The Secret of Why We Are Here

The Brit Milah this Shabbat was a powerful reminder that we are all architects of a “personal tabernacle.” Every act of kindness, every moment of ethical restraint in business, and every tear shed for a neighbor is an “eighth-day” act.

As we watched the newest member of the Jewish people enter the covenant on the very day named for the number eight, the message was clear: our lives are not a choice between the body and the soul. Rather, our purpose is to merge the two.

This is the secret of our existence. G-d placed our spiritual souls into physical bodies so that we might direct and channel the material world toward the Divine. By making our base world holy, we fulfill the very meaning of life itself.
