‘You Want it Darker’ Parashat Bo 5786

The Portion of Bo is about darkness, the kind that breaks systems. The Torah describes a cascade when a civilization confuses its source of light. Locusts cover the land until [Shemot 10:15] “it is darkened,” stripping Egypt of green and hope. Pharaoh finally begs Moshe to remove [Shemot 10:17] “this death,” a famine on a blackened horizon. Next comes darkness [Shemot 10:21–23]: “[The Egyptians] did not see one another and no one rose from his place for three days, while Israel had light in its homes.” The sequence culminates at midnight when the firstborn die [Shemot 12:29–30]: “There was a great outcry, for there was not a house without someone dead.” Read together, this is a progression from degraded visibility to paralysis to the termination of life. Egypt’s own officials warn Pharaoh [Shemot 10:7]: “Do you not yet understand that Egypt is ruined?” When the instruments say the system is failing and you still cannot see it, darkness is already in the machine. This is not random punishment but pedagogy aimed at Egypt and at us. The Torah tells this story in the language of sight so that we will audit our own sources of light before the cascade begins.

To understand what is going on, we must speak Egyptian for a moment. In their cosmos, light meant existence and order; darkness meant chaos and the edge of nonbeing. Each night the sun‑god Ra sailed the Duat and battled Apophis, the world‑encircling serpent. If Apophis prevailed, dawn would not come. Now let’s return to the eighth plague: the locusts do not merely eat, they darken the land until not a green thing remains. Pharaoh’s “remove this death” confesses that in a world where light is life, a blackened landscape is death already moving. The Torah also reminds us from the outset that light is not solar property but [Bereishit 1:3–4] a spoken word of G-d.

The ninth plague makes it explicit [Shemot 10:21]: “A darkness that can be felt” means more than vision loss. Orientation and relationship are cut off. People do not see one another and do not rise for three days. When a society’s supposed light fails, movement stops, communication collapses, initiative dies. Then comes a verse that changes everything [Shemot 10:23]: “But all the children of Israel had light in their dwellings.” Same time, same land, different homes. Egypt has a theological problem, not a technical one. G-d is allocating light and making a distinction Egypt does not know how to make. Stage one: the horizon goes dark and inputs collapse. Stage two: the interior goes dark and actors freeze. Stage three is coming unless the assumption is updated. G-d asks: Do your lights help you see people and move toward them, or do they isolate you? If your light isolates you, then it is not light.

After three days of blindness, Pharaoh tries to reassert control with sight [Shemot 10:28–29]: “Do not see my face again, for on the day you see my face you will die,” and Moshe replies, “You have spoken well. I will not see your face again.” The triple “see” is not accidental. Pharaoh casts himself as a false sun, claiming sovereignty over life and death through visibility, precisely when he has lost the power to see. Only G-d has shown command over light and darkness, allocating them in adjacent neighbourhoods. Moshe does not argue. He disengages. This is the model: You do not outshout a false sun; you stop orbiting it. Many of us know the inner Pharaoh who makes presence and visibility conditions for life. The reply that shuts it down is the one Moshe uses: I will not see your face again.

Then comes midnight. According to ancient Egyptian cosmology, this is when darkness is the strongest. Exactly then the tenth plague lands [Shemot 12:29–30]: “It came to pass at midnight that G‑d struck all the firstborn in the land of Egypt… There was a great cry in Egypt, for there was not a house where there was not someone dead.” This is not a case of chaos winning – it is judgment, exact and bounded. Darkness does not run amok – it is wielded by G-d with precision. The same G-d who separated light from darkness at creation now separates Israel from Egypt at redemption. The One who said “Let there be light” now says “Let there be a boundary”. Israel leaves Egypt at night under pillars of fire and cloud. Even in the dark, you can see where to go if you follow the right light.

Seen together, the final three plagues model three different ways darkness can be created, each more severe than the last. Locusts do not eliminate light itself; they block it. The sun still shines, but the land cannot receive it. Vision degrades because the horizon is occluded and the future is eaten away. The plague of darkness goes further: it does not obstruct light but turns it off. “A darkness that can be felt” is a system‑wide blackout in which orientation, motion, and relationship cease even though nothing physical has been destroyed. People cannot see one another and therefore cannot move. The death of the firstborn is the final escalation. Here the lights are neither blocked nor switched off selectively; rather, the entire power system collapses at once. Midnight is not merely absence of light but the moment when every household loses its prime mover, its continuity, its future. Locusts blind by saturation, darkness paralyses by deprivation, and the tenth plague communicates that when false sources of power are left in place long enough, the shutdown becomes total. Egypt experiences not random suffering but a controlled demonstration of how systems fail when they mistake control, abundance, or hierarchy for true illumination.

A modern song feels written for this episode. Leonard Cohen’s “You Want It Darker” turns on a stark refrain and a readied answer” “You want it darker, We kill the flame… Hineni, hineni, I’m ready, my L-rd”. The choral “Hineni (I am here and ready)” puts a biblical here‑I‑am on the singer’s lips, while “we kill the flame” calls out our willingness to extinguish the light when we prefer not to face what it reveals. When read beside the plagues, the song is a mirror. Pharaoh wants it darker and keeps dimming the world, even after the land is black with locusts and after three days without sight. He kills the flame and calls it sovereignty. Israel learns to say Hineni to G-d’s call and to carry a different light, one that does not depend on a throne or a sunrise. The question Cohen leaves us with is the Torah’s too: When the world pressures us toward night, do we join the chorus that kills the flame, or do we become the dwellings where G-d’s light still burns? That word Hineni echoes across the Torah when a human being steps into responsibility before G-d: Abraham answers Hineni at the Akeidah, Jacob in the night visions, and Moshe at the burning bush. Each Hineni is a refusal to kill the flame. It is a pledge to stand as a bearer of light even when the terrain is dark and the demands are great. Cohen’s chorus sounds like a late‑life[1] Hineni, an acceptance that the path through darkness is still walked face forward, under command, with the flame protected rather than snuffed.

And so the Torah comes from Pharaoh’s palace straight into our homes. Darkness will come. Projects will fail. Markets will turn. Health will break. Friendships will fray. But darkness does not decide the outcome. Systems fail when they rely on the wrong light. When illumination isolates rather than connects, when visibility replaces moral vision, when control replaces covenant, Egypt’s stages repeat: first the colour drains, then movement ceases, and finally the bill arrives at midnight. The counter‑practice is old and urgent: Keep light in your dwellings. Make the home the first theatre of distinction. Ask whether your light helps you see people and obligations, whether it moves you toward performing G-d’s Will and whether it aligns with the Voice that once said “Let there be light”. When Moshe stops looking at Pharaoh, a nation begins walking toward dawn. May G-d grant us the clarity to recognize failing light early and the courage to align our lives with His light, so that even at our darkest hour we will know which way to walk and, when morning comes, we will recognize it.

Shabbat Shalom,
