Parashat Tzav returns us to the altar again and again, to the rhythms of sacrifice, to the quiet, repetitive work of the priests. And at its center is one of the Torah's simplest and most powerful instructions: "Esh tamid tukad al hamizbe'ach, lo tichbeh" — "A perpetual fire shall be kept burning on the altar; it must not go out" (Leviticus 6:6).
Not a towering fire or an occasional blaze, but a constant one.
There is something almost counterintuitive about that. We tend to associate holiness with acute intensity—with peak moments, with lofty inspiration, and with experiences that lift us out of the ordinary. But Tzav insists that the real work is not in those moments. It is in what continues the next morning, and the morning after that.
The fire must keep going.
I've been thinking about that lately in a very embodied way. For a while now, I've had a very occasional yoga practice. When I would get to the end of the day or wake up in the morning with energy to spare, I'd turn on a video and try my best to follow along. And, it wasn't anywhere near a consistent practice. Some days I'd do more, some days less, most days not at all. The practice was there—but not steady.
Lately, that's shifted.
Most mornings now, I wake up with a stiff lower back—a quiet but persistent reminder that my body has its own timeline. With my birthday this week, I'm becoming more aware of that gap between how I imagine myself and how my body actually feels when I get out of bed. And so, I've become more diligent. Not extreme, and definitely not intense—just more consistent. Fifteen to thirty minutes each morning. Stretching, strengthening, showing up.
And what I've noticed is not dramatic. There's no single day when everything suddenly feels different. But over time, there is a marked improvement. Less stiffness. More strength. A sense that my body is responding—not to intensity, but to reliability.
That has begun to feel a bit like an esh tamid.
Because the Torah doesn't ask for a fire that burns bright and then burns out. It asks for a fire that keeps going. The priests don't rely on the spark of ignition—they return to tend the fire every day. They sustain it and make sure that even as it fluctuates, it never fully disappears.
There's a subtle but profound distinction there. It's not that intensity has no place. There are moments in life that call for it. But intensity alone cannot sustain anything—not our bodies, not our relationships, not our spiritual lives.
What sustains us is consistency. Not perfection, but return. Not dramatic change, but accumulated care.
And sometimes, the shift is not from nothing to something, but from something to something steadier. From a practice that exists to a practice that holds.
Lately, I find myself paying attention to that shift. The realization that I can't rely on bursts of energy in the same way I once did—but also, that I don't need to. There is another path, one that is quieter but more enduring. A path of tending rather than igniting.
Maybe that's what this parashah is teaching us.
Where, in our lives, do we already have a "fire," something meaningful, something present—but one that could be tended more consistently? Where might a little more diligence, a little more regularity, make all the difference?
Esh tamid is not about starting from scratch. It's about not letting something valuable flicker out through neglect.
The fire on the altar didn't need to be extraordinary. It just needed to be sustained.
And maybe that's the deeper invitation of Tzav—not to chase the highest flames, but to become the kind of people who know how to keep them burning.
