How Did Sarah’s Miraculous Milk Extend the Blessing of Yitzchak to the World?
After the birth of Yitzchak, Sarah exclaims:
ספר בראשית פרק כא פסוק ז וַתֹּאמֶר מִי מִלֵּל לְאַבְרָהָם הֵינִיקָה בָנִים שָׂרָה כִּי יָלַדְתִּי בֵן לִזְקֻנָיו:
“She said, ‘Who would have said to Avraham that Sarah would nurse children? For I have borne a son in his old age’” (Bereishit 21:7).
The miracle of Yitzchak’s birth had been foretold, but Sarah’s ability to nurse had not been explicitly promised. A 90-year-old woman giving birth was miraculous enough. Why was an additional miracle necessary for Sarah to produce milk when Yitzchak could have been nourished by a nursemaid? Moreover, why does it state that Sarah nursed children in plural?
Rashi explains that the plural expression בָנִים/banim – “children” – is deliberate. At the feast celebrating Yitzchak’s weaning, noblewomen brought their babies to Sarah, and she nursed them. By publicly demonstrating that she truly was Yitzchak’s mother, she disproved the claim that she had merely brought home an abandoned child (Rashi, Bereishit 21:7). The Midrash adds that when Sarah revealed her breasts, they flowed with milk “like two wellsprings.” Therefore, the women desired their children to merit nourishment from this righteous woman (Midrash Bereishit Rabbah 53:9).
Sarah’s miraculous milk was not only about nourishing Yitzchak. The blessing overflowed beyond her own son to nourish others. Perhaps this is why the Torah emphasizes not merely that Sarah nursed a son, but that “Sarah would nurse children.” The miraculous nourishment that accompanied the birth of the first child destined to continue the covenant was never intended to be confined to the Jewish family alone. The blessing flowing through Sarah had the power to influence the wider world.
Yet Sarah did not nourish other children at her own son’s expense. She waited until he had been fully weaned before nursing the other children, so that she would not diminish the portion intended for this tzaddik (HaGriz Halevi, Bereishit 21:7). This teaches us an essential principle of true giving: universal generosity must grow from a strong and properly nourished Jewish home. Only after ensuring that Yitzchak received everything he needed could Sarah’s overflowing nourishment extend outward. On Rosh Hashana, we too ask Hashem for abundant blessing. Yet perhaps we can ask ourselves: When Hashem fills us with blessing, how can we allow it to overflow and nourish others?
How Can Hashem Open Our Eyes to the Wellspring that Was There All Along?
The second form of miraculous nourishment in our Torah reading appears at the opposite extreme. Sarah’s breasts overflow with milk, while Hagar’s flask becomes completely empty. Wandering in the wilderness with Yishmael, Hagar reaches the terrifying moment when there is nothing left for her child to drink:
ספר בראשית פרק כא פסוק יט וַיִּפְקַח אֱלֹהִים אֶת עֵינֶיהָ וַתֵּרֶא בְּאֵר מָיִם וַתֵּלֶךְ וַתְּמַלֵּא אֶת הַחֵמֶת מַיִם וַתַּשְׁקְ אֶת הַנָּעַר:
“G-d opened her eyes, and she saw a well of water; she went and filled the flask with water and gave the youth to drink” (Bereishit 21:19).
The verse does not state that Hashem created a well. He “opened her eyes,” and then she saw it.
Be’er Mayim Chayim explains that the water was already there, but Hagar could not see it until Hashem opened her eyes. This teaches us something profound about Divine nourishment. We may believe that what we need does not exist because we cannot presently perceive it. Yet the source of our salvation may already be right before us, waiting for Hashem to open our eyes.
The Midrash derives from Hagar’s experience that everyone is presumed blind until Hashem opens their eyes (Midrash Bereishit Rabbah 53:14). Our physical eyes may function perfectly, while our spiritual vision remains obstructed. We see the empty flask but not the well. We see what is missing but not the hidden source from which Hashem can replenish it.
This is especially relevant on Rosh Hashana. Standing before Hashem at the beginning of the year, we cannot see what lies ahead. We do not know from where our livelihood, healing, strength, or salvation will come. Like Hagar in the wilderness, we may see only the limitations of our present circumstances.
Yet Yishmael’s salvation teaches us that Hashem judges us בַּאֲשֶׁר הוּא שָׁם/ba’asher hu sham – “where he is now.” Although the angels protested because of what Yishmael’s descendants would eventually do, Hashem judged him according to his present state (Rosh Hashana 16b; Rashi, Bereishit 21:17).
This message lies at the heart of Rosh Hashana. We do not have to remain imprisoned by what we have been or by what others expect us to become. Hashem looks at us where we are now. Through prayer and teshuvah, we can stand before Him anew. Then the well that we could not see may suddenly become visible.
How Does Avraham Transform Physical Nourishment into Awareness of Hashem?
After the miraculous nourishment of Sarah’s milk and Hagar’s well, the Torah introduces a third form of nourishment – the food that one human being consciously provides for another:
ספר בראשית פרק כא פסוק לג וַיִּטַּע אֵשֶׁל בִּבְאֵר שָׁבַע וַיִּקְרָא שָׁם בְּשֵׁם הָשֵׁם אֵל עוֹלָם:
“Avraham planted an eshel in Be’er Sheva, and there he called in the Name of Hashem, G-d of the universe” (Bereishit 21:33).
Our Sages differ regarding the nature of this eshel. According to one opinion, it was an orchard from which Avraham supplied his guests with fruit. According to another, it was an inn where travelers could eat and lodge (Rashi, Bereishit 21:33; Sotah 10a).
According to Rabbeinu Bachaya, the letters אשל/eshel allude to אכילה/achilah – eating, שכיבה/shechivah – sleeping, and לויה/levayah – escorting. These same letters form שאל/sha’al – “ask.” Avraham would invite each traveler, “Ask what I can give you,” and provide whatever he needed (Rabbeinu Bachaya, Bereishit 21:33).
Yet Avraham’s hospitality was not merely philanthropy. The Torah immediately connects his eshel with calling in the Name of Hashem. After his guests had eaten and drunk, Avraham would tell them, “Bless the One from Whose possessions you have eaten! Do you think you have eaten from mine? You have eaten from the One Who spoke and the world came into existence” (Sotah 10a).
Avraham transformed eating into spiritual awareness.
Adam HaRishon’s relationship with food brought concealment into the world when he ate from the forbidden Tree. Avraham’s relationship with food began to repair that rupture. He planted, fed, nourished, and then revealed the Divine Source within the physical abundance. Rather than allowing food to make people forget Hashem, Avraham used food itself to help them recognize Him.
This is a central message of Rosh Hashana. We proclaim Hashem as King not only in the synagogue through prayer and shofar. His Kingship must penetrate the most physical dimensions of our lives. Every fruit, every glass of water, and every meal can become an opportunity to recognize אֵל עוֹלָם/Kel Olam – the Divine presence that sustains the entire world.
How Can the Blessing Resting on Our Food and Possessions Nourish Others?
The fourth manifestation of nourishment in our Torah reading appears during Avraham’s covenant with Avimelech:
ספר בראשית פרק כא פסוק לג וַיִּטַּע אֵשֶׁל בִּבְאֵר שָׁבַע וַיִּקְרָא שָׁם בְּשֵׁם הָשֵׁם אֵל עוֹלָם:
“Avraham planted an eshel in Be’er Sheva, and there he called in the Name of Hashem, G-d of the universe” (Bereishit 21:33).
Why would a wealthy king need Avraham’s sheep and cattle?
Be’er Mayim Chayim explains that Avimelech was not seeking the material value of Avraham’s animals. He desired the blessing that rested upon them. A person who is blessed transmits blessing to his possessions. Avraham therefore gave Avimelech from his own sheep and cattle so that Avimelech’s livestock and endeavors would become blessed through Avraham’s merit.
This fulfills Hashem’s original promise to Avraham:
וֶהְיֵה בְּרָכָה
“And you shall be a blessing” (Bereishit 12:2).
Avraham does not merely receive blessing. He becomes a source through which Hashem’s blessing reaches others.
We can now see a remarkable progression throughout the chapter. Sarah receives miraculous nourishment within her own body, which overflows to other children. Hagar discovers that Hashem’s life-giving water is present even when she cannot see it. Avraham takes the physical nourishment of his orchard and hospitality and consciously reconnects it to its Divine Source. Finally, the blessing becomes so deeply embedded in Avraham that even the animals he gives away can transmit blessing to another person.
This may be one of the deepest messages of nourishment in the Rosh Hashana Torah reading. We begin by recognizing that Hashem nourishes us. Yet our ultimate purpose is not merely to receive His blessing. It is to become vessels through which His blessing can flow into the world.
How Can We Become Channels of Hashem’s Nourishment in the Coming Year?
Rosh Hashana celebrates the creation of humanity and the coronation of Hashem as King over the entire world. It is therefore fitting that its Torah reading repeatedly teaches us that all nourishment ultimately flows from Him.
Sarah teaches us that Hashem can bring forth nourishment even where nature declares it impossible – and that true abundance overflows to nourish others.
Hagar teaches us that Hashem’s wellspring may already be present even when we cannot see it. We pray that He open our eyes to recognize the blessings and possibilities hidden before us.
Avraham’s eshel teaches us not to stop at receiving Hashem’s bounty. By feeding others and revealing the Divine Source of our food, physical nourishment itself can proclaim Hashem’s Kingship.
Finally, Avraham’s sheep and cattle teach us what it means to become a blessing. When we connect ourselves deeply to Hashem, His blessing can become embedded in everything entrusted to us and extend from us to others.
On Rosh Hashana, we ask Hashem to inscribe us for life, sustenance, health, and blessing. Yet perhaps the Torah reading invites us to ask for something even greater: May the nourishment Hashem grants us not stop with us. May He open our eyes to His hidden wellsprings, enable us to nourish those entrusted to our care, inspire us to share His abundance generously, and transform us into channels through which His blessing flows into the entire world.
