Every Passover, Jews around the world gather to retell the story of the Exodus. Yet Passover is not merely a commemoration of a past event—it is, at its core, a moral program. In an age when social justice movements often speak of “solidarity” and “allyship,” the Torah offers a strikingly different framework: not a choice to stand with the oppressed, but a command rooted in what we ourselves have lived.

What makes this structure so remarkable is that it rejects the notion that there is a distinction between serving God and pursuing justice. In the Torah’s vision, these are not two separate demands pulling in different directions. Freeing slaves, protecting the stranger, leaving gleanings for the poor: they are not acts of justice that accompany religious life, they are religious life. The liberation from Egypt did not end with freedom; it began with it. This is why every generation is called not merely to remember the Exodus, but to reenact it—to extend its logic to all who remain in bondage.

The Recurring Formula

At the heart of Deuteronomy’s legal code lies a recurring formula. Five times, in contexts ranging from labor law to harvest regulations, the Torah interrupts its legislation with the same reminder: “Remember that you were a slave in the land of Egypt.” The first occurrence is embedded in the Ten Commandments themselves:

Observe the Shabbat day and keep it holy… you shall not do any work—you, your son or your daughter, your male or female slave, your ox or your ass, or any of your cattle, or the stranger in your settlements, so that your male and female slave may rest as you do. Remember that you were a slave in the land of Egypt and the Eternal your God freed you from there with a mighty hand and an outstretched arm; therefore the Eternal your God has commanded you to observe the Shabbat day (Deuteronomy 5:12-15).

The mandate is striking: rest is commanded not only for oneself, but explicitly for those who cannot rest of their own volition—slaves, workers, even animals. And the reason given is not God’s rest on the seventh day of Creation, as in the Exodus version of the Decalogue, but the memory of Egyptian bondage. The four remaining occurrences (Deuteronomy 15:12-15; 16:11-12; 24:17-18 and 19-22) follow the same logic, each anchoring a different social law to the same foundational experience.

What unites these five laws? At first glance, they address very different situations: Shabbat rest; the release of debt-slaves in the seventh year; the inclusion of the marginalized in festival celebrations; the protection of strangers, orphans and widows from legal injustice; and the obligation to leave gleanings of the harvest for those without resources. Yet they share a common thread. Each addresses a form of structural powerlessness—those who cannot advocate for themselves, who have no protector, who stand outside the circles of power and ownership. The servant cannot refuse work; the debtor cannot escape bondage; the stranger has no standing in court; the poor have no claim on another’s harvest.

The Torah does not command us to help the vulnerable because it is kind to do so. It commands us because we know—from the inside—what it is to be powerless. The “al ken—therefore” formula (present in four of the five occurrences) makes this explicit. The causality runs from memory to obligation: because you were a slave, you are now commanded. 

The Logic of the Transfer

At first glance, the transfer from slave memory to legal obligation seems straightforward. The Israelites were strangers in Egypt before they were enslaved—so the command to protect the stranger feels almost self-evident. But the Torah’s logic reaches further. The same memory—“you were a slave in the land of Egypt”—also grounds obligations toward the orphan, the widow, the debtor, the poor who glean the edges of someone else’s field. These are not people whose situation resembles slavery in any obvious way. Why should the experience of Egyptian bondage generate obligations toward them?

Ramban, in his commentary on Exodus 22:20, locates the answer not in law but in psychology. The Torah, he writes, is not simply asking us to remember a historical fact—it is asking us to remember a feeling: the feeling of having no one to turn to. As he puts it, “every stranger feels depressed, and is always sighing and crying, and his eyes are always directed towards God.” The cries of the Israelites in Egypt reached God’s ear—not because of their merits, but simply on account of their bondage. What slavery taught us was not merely what it feels like to do forced labor; it taught us what it feels like to be utterly without protection.

This is the key to the transfer. The five laws address five forms of structural powerlessness—those who cannot refuse work, cannot escape bondage, have no advocate in court, no share in the harvest, no place at the table of communal celebration. What unites them is not their specific situation but their position: they are those who have no protector, whose only recourse is the mercy of others—or of God.

This is why the Haggadah insists that every generation must experience the Exodus as if it happened to them personally. The Seder is not a commemoration of vulnerability—it is a rehearsal. We eat the bread of affliction, we taste the bitterness of slavery, we retell the story in the first person, precisely so that the moral imagination generated by the Exodus does not go cold. To enact the Exodus each year is to ensure that the obligation it commands remains alive in each generation.

One and Only Act

But if slavery teaches us to recognize structural powerlessness, a deeper question remains: to which category does the obligation it generates belong? Is protecting the powerless an ethical duty, or an act of divine service? The first of our five pesukim—the Shabbat commandment in Deuteronomy—makes for a revealing test case, because the same law appears twice in the Torah with two different justifications. In Exodus (20:11), Shabbat is grounded in Creation; here in Deuteronomy, it is grounded in the Exodus from Egypt. How can the same commandment rest on such different foundations?

Rambam, in the Moreh Nevuchim (2:31), argues that this difference is intentional and that each reason serves a distinct purpose: 

In the former, the cause of the honour and distinction of the day is given… But the fact that God has given us the law of the Sabbath and commanded us to keep it, is the consequence of our having been slaves; for then our work did not depend on our will, nor could we choose the time for it; and we could not rest. 

For Rambam, then, Shabbat is a double blessing: it confirms the theological truth of Creation, and it memorializes God’s kindness in freeing us from bondage. The ethical and the theological sit side by side, each with its own logic.

Ramban (on Deuteronomy 5:15) finds this unsatisfying. When we rest on Shabbat, he argues, nothing in the act of resting naturally evokes Egypt—no one observing us at rest would think of the Exodus. For Ramban, the two justifications are not parallel but convergent: both Creation and Exodus point to the same God, the One who has sovereign power over history and nature alike. The Exodus does not add a second reason for Shabbat—it deepens the first. Remembering Egypt confirms what Shabbat already declares: that there is a God who acts, who intervenes, who liberates.

I believe both commentators are right—and their apparent disagreement dissolves on closer inspection. The “al ken” does not choose between the theological and the ethical; it fuses them. Shabbat is not either a memorial of Creation or a social justice imperative—it is both, simultaneously, because in the Torah’s vision, these are not two different things. To rest, and to ensure that all those in your household rest with you, is a single act of divine service. We cannot observe Shabbat while our servants labor—that would be performing the ritual while betraying its meaning. And we cannot practice justice without grounding it in the God who liberated us—that would be to perform ethics while disavowing its source. The “al ken” holds the two together, indissolubly. Serving God through Shabbat and serving God through justice toward the powerless are not two acts, they are one.

Renewed Obligation

Much of contemporary activism speaks of solidarity—a choice to stand with the oppressed, a commitment one makes freely and can equally freely revoke. There is nobility in that choice, because it is born only of free will and one’s internal moral compass. But the Torah offers a different model entirely. It does not invite us to stand in solidarity with the powerless. It commands us to protect them, and it grounds that command in something we cannot undo: what we experienced ourselves, and what God did for us.

The “al ken” makes the causality explicit—but it is not the causality of debt. The Torah does not say: God freed you, therefore you owe; it says: you suffered, therefore you understand. The experience of bondage did not create a liability—it created a moral imagination, the capacity to recognize powerlessness in others because we have inhabited it ourselves. And as the debate between Rambam and Ramban reveals, this moral imagination cannot be separated from theology: to enact justice toward the powerless is not merely an ethical duty but an act of divine service, commanded by the same God who once heard the cries of the enslaved in Egypt.

Yet the Torah does not trust memory alone. This is why the Haggadah insists that every generation must experience the Exodus as if it happened to them personally—not as a historical exercise, but as a renewal of commitment. Each Seder is not a commemoration but a recommitment: to the memory of bondage, to the God who liberated us, and to the obligations that follow. The obligation does not diminish with time. It is designed to be rekindled, year after year, by a people who know from the inside what it means to have no protector—and who have chosen, ever since, to be one.
