Lech Lecha: A journey toward possibility.

For more discussion

PARASHAT LECH LECHA | לֶךְ־לְךָ · Shabbat, October 24, 2026 · 13 Cheshvan 5787 · Genesis 12:1–17:27

Two small phrases in this week’s parsha open unusually large questions: Is a call to leave also a promise of personal growth? And can a person move beyond a future that seems already written? These notes distinguish the Torah’s plain wording from the creative readings of our sages.

Gem 1 — The journey that is “for your own good”

Start with the Torah: Genesis 12:1

וַיֹּאמֶר יְהוָה אֶל־אַבְרָם לֶךְ־לְךָ מֵאַרְצְךָ וּמִמּוֹלַדְתְּךָ וּמִבֵּית אָבִיךָ אֶל־הָאָרֶץ אֲשֶׁר אַרְאֶךָ׃

G-d said to Abram: “Go from your land, your birthplace, and your father’s house to the land that I will show you.” (Our translation.)

Why are there two words: lech lecha?

In Hebrew, lech is the command “go”; lecha literally means “for you” or “to you.” Rashi hears something extra in that second word: G-d is not only commanding a difficult departure but promising that the move will ultimately be for Abram’s benefit. The blessing in the next verse—becoming a great nation—helps explain why.

Rashi’s reading (Genesis 12:1)

Rashi writes: לַהֲנָאָתְךָ וּלְטוֹבָתְךָ — “for your benefit and for your good.” He adds that Abram will merit descendants and become known in the world through this journey. Rashi draws on rabbinic tradition (including Rosh Hashanah 16b and Midrash Tanchuma, Lech Lecha 3).

Notice the tension: what feels like loss at the start of the journey may become a blessing in retrospect. Rashi is not claiming that leaving home is painless. He is asking us to read the command in light of its promised destination.

A textual detail worth noticing

G-d does not reveal the destination by name. Abram is told to go “to the land that I will show you.” The sequence is unusual: he must begin moving before the entire route is known. That makes the command both a physical journey and, for later readers, a model of trust amid uncertainty.

Gem 1 — Reading the same words differently

Ramban disagrees with the need for a special reading

Ramban (Nachmanides), commenting on Genesis 12:1, cites Rashi’s “for your benefit” explanation but then argues that the added lecha need not carry a special hidden meaning. He treats it as a natural Hebrew expression. In other words, the Torah may simply be saying “go.”

This is a productive disagreement, not a contradiction about the story. Rashi gives the phrase a midrashic or homiletical resonance; Ramban reminds us to take Hebrew grammar seriously. The two approaches ask different questions: What does the wording ordinarily mean? And what moral or spiritual teaching can its wording invite?

Why “your land, your birthplace, your father’s house”?

The verse names three circles of belonging. A reader can hear them as geography, community, and family identity. Whether or not that is the verse’s original intention, it provides a powerful framework for discussing how change touches different parts of a life. The challenge is not merely moving on a map; it is releasing familiar definitions of who we are.

One more twist: Rashi on Genesis 12:2

Rashi observes that travel can threaten three things—family growth, possessions, and reputation. He connects G-d’s three blessings to those very risks. In this reading, the promise addresses the concrete costs of leaving, not just an abstract ideal of courage.

At the Shabbat table — Gem 1

• Does the promise “for your good” make a hard decision easier—or can it make the challenge more demanding?
• What is gained when G-d leaves Abram’s destination unspecified? Would you prefer certainty before acting?
• When should we favor Rashi’s deeper moral reading, and when is Ramban’s plain-language reading more convincing?
• Which is hardest to leave behind: a place, a community, or a familiar identity?

A bridge to the second gem

The first teaching begins with leaving an old place. The second is about leaving an old prediction. Both suggest that what we think is fixed may not define what comes next.

Gem 2 — Did Abraham outgrow his horoscope?

Start with the Torah: Genesis 15:5

וַיּוֹצֵא אֹתוֹ הַחוּצָה וַיֹּאמֶר הַבֶּט־נָא הַשָּׁמַיְמָה וּסְפֹר הַכּוֹכָבִים אִם־תּוּכַל לִסְפֹּר אֹתָם וַיֹּאמֶר לוֹ כֹּה יִהְיֶה זַרְעֶךָ׃

G-d brought Abram outside and said: “Look toward the heavens and count the stars, if you can count them.” Then G-d said: “So shall your descendants be.” (Our translation.)

The plain meaning: a promise beyond counting

Abram is worried that he has no child to inherit from him (Genesis 15:2–3). G-d reassures him that a child of his own will be his heir (15:4), then uses the stars as an image of an enormous future family (15:5). On the straightforward level, “outside” means outside the tent to see the sky.

Rashi’s surprising Midrash

Rashi explicitly separates the straightforward reading from a midrashic one. In the Midrash, G-d tells Abram to “go out” of his astrological calculations. Abram believes the stars predict that he will never have a son. G-d answers that his future is not limited by that prediction. Rashi even links the later changes from Abram to Abraham and Sarai to Sarah with a transformed future.

This is a rabbinic interpretation of the words “He brought him outside,” not an explicit Torah report that Abram consulted an astrologer. That distinction matters: the surprise is what the sages read into the phrase.

The Talmud expands the theme (Shabbat 156a–b)

The Gemara discusses the saying ein mazal le-Yisrael — commonly rendered “Israel is not bound by a fixed constellation.” One opinion connects this teaching to Abram’s encounter with the stars. The sugya also records other positions, so it should not be flattened into a simple unanimous declaration about astrology.

For a contemporary study discussion, the point need not be whether astrology works. The moral question is whether fear, prediction, or social expectation can become a self-imposed boundary on hope and responsibility.

Gem 2 — A new name, a new horizon

Start with the Torah: Genesis 17:5

וְלֹא־יִקָּרֵא עוֹד אֶת־שִׁמְךָ אַבְרָם וְהָיָה שִׁמְךָ אַבְרָהָם כִּי אַב־הֲמוֹן גּוֹיִם נְתַתִּיךָ׃

“You shall no longer be called Abram; your name shall be Abraham, for I make you the father of a multitude of nations.” (Our translation.)

The renaming happens later in the portion, in Genesis 17. Rashi’s reading of the earlier star scene connects the two moments. The name change signals an expanded calling, not merely a change in spelling. Genesis 17:15 likewise changes Sarai’s name to Sarah.

A useful counterpoint: blessing does not erase struggle

The Torah does not depict the promise as immediately fulfilled. Abram continues through years of waiting, family complexity, and uncertainty. The Midrash’s message is therefore not “believe strongly enough and every wish will come true.” It is narrower and richer: the limits we perceive are not always the limits of possibility.

At the Shabbat table — Gem 2

• Why might the Midrash transform a physical movement outside a tent into a challenge to move outside one’s assumptions?
• Can an encouraging prediction trap us just as much as a discouraging one?
• How can we distinguish hopeful openness from unrealistic certainty?
• What do the names Abram/Abraham and Sarai/Sarah tell us about the relationship between identity and destiny?

Bring the two gems together

“Lech lecha” asks Abram to leave a familiar world; “He brought him outside” asks him, in the Midrash, to leave a familiar forecast. Both stories ask us to take one step beyond a boundary that once seemed permanent.
