Moshe's hands reflect Yisrael's readiness

בפסוק והיה כאשר ירים משה ואמרו חז"ל וכי ידיו של משה עושות מלחמה או שוברות אלא לומר לך בזמן שישראל מסתכלין כלפי מעלה ומשעבדין את לבם לאביהם שבשמים היו מתגברין ואם לאו היו נופלין.

On the verse "And it was, when Moshe raised his hand [Yisrael prevailed]," Chazal said: did the hands of Moshe make war or break it? Rather, it comes to tell you that when Yisrael looked upward and subjugated their hearts to their Father in Heaven, they prevailed; and if not, they fell.

The Mishnah famously asks how Moshe's raised hands could decide the battle against Amalek, and answers that they were a sign: victory depended on whether Yisrael turned their hearts upward in submission to Hashem.

וקשה מה קושיא וכי ידיו של משה.

And it is difficult: what is the question, "did the hands of Moshe…"?

The Sefas Emes presses on the Mishnah's own wording: why is it self-evidently impossible that Moshe's hands wielded power?

וכי זה בלבד עשו לנו ידיו של משה.

Did the hands of Moshe do only this for us?

After all, Moshe's hands accomplished far greater things — so why should it seem strange that they would influence this battle?

והם עשו כל נפלאות ה' בקי"ס ושאר נסים.

And they performed all the wonders of Hashem at the splitting of the sea and the other miracles.

Those same hands split the Yam Suf and wrought many other miracles — so the Mishnah's incredulity at the idea that they could affect the war seems puzzling.

וכי ידיו של משה מילתא זוטרתי נינהו.

Are the hands of Moshe a small matter?

The hands of Moshe Rabbeinu are surely no trivial thing; why then does the Mishnah dismiss the notion that they could "make war"?

ותו מה דמסיים המשנה ואם לאו היו נופלין.

And further, [there is a difficulty with] what the Mishnah concludes: "and if not, they fell."

A second difficulty: the Mishnah ends by saying that when Yisrael failed to look upward, "they fell" — but the verse never speaks of Yisrael falling.

ונפילת ישראל מאן דכר שמי'. וגבר עמלק כתיב ולא נפילת ישראל.

Where is the falling of Yisrael even mentioned? It is written "and Amalek prevailed," not "and Yisrael fell."

The Torah only says "Amalek prevailed," not that Yisrael "fell." So why does the Mishnah introduce the language of Yisrael's "falling"?

לכן נראה לפרש כוונתם בדרך זה.

Therefore it appears to explain their intention in this way.

To resolve both difficulties, the Sefas Emes offers a new reading of the Mishnah.

דהקושיא וכי הי' תלוי כל זה במשה רע"ה עצמו שידיו עושות או שוברות דא"כ פשיטא דלא הי' מניח ידיו ומאי כאשר יניח משה.

That the question is: was all this dependent on Moshe Rabbeinu himself, that his hands "make" or "break"? For if so, it is obvious that he would never lower his hands — so what is the meaning of "when Moshe would let his hand down"?

The Mishnah's real question is not whether hands can wage war, but whether the outcome hinged on Moshe alone. If it did, he would obviously never lower his hands and let Yisrael lose — so the verse's mention of his hands going down shows the matter did not depend on him.

לכן תירצו כי ידיו של משה היו מתגברין כשבנ"י מסתכלין כלפי מעלה.

Therefore they answered that the hands of Moshe themselves grew strong when Bnei Yisrael looked upward.

The resolution: it was Moshe's own hands that were strengthened or weakened, and that depended on Bnei Yisrael. When they turned their hearts heavenward, his hands were lifted with strength.

וא"ל היו נופלין ידיו של משה רע"ה. ולא הי' יכול להרימם.

And if not, the hands of Moshe Rabbeinu would fall, and he could not raise them.

This is the "falling" the Mishnah meant — not the falling of Yisrael, but of Moshe's hands. When Yisrael did not look upward, his hands literally dropped, and he was powerless to lift them.

כי מרע"ה הגם כי הוא הי' מושיע לבנ"י. אבל הכל הי' תלוי בהכנת בנ"י.

For Moshe Rabbeinu, although he was the savior of Bnei Yisrael, nonetheless everything depended on the preparation [hachanah] of Bnei Yisrael.

Even though Moshe was the channel of deliverance, his very ability to act drew entirely from the spiritual readiness of the people; the power flowed up from them to him.

כי כל נשיאי ישראל בכחן של בנ"י הם נושאים כמ"ש במקום אחר כמו שכ' ארון נשא את נושאיו.

For all the leaders [nesi'im] of Yisrael bear [their office] by the power of Bnei Yisrael, as we have said elsewhere, like that which is written: "the Aron carried those who carried it."

Every Jewish leader holds his position through the spiritual strength of the people he leads — just as the Aron, though seemingly carried by the Levi'im, in truth carried them. The leader is uplifted by those he serves.

כן הוא בבנ"י דומין לבוראן.

So it is with Bnei Yisrael, who resemble their Creator.

In this respect Bnei Yisrael mirror their Creator: just as Hashem sustains all yet needs nothing, the nation sustains and elevates its own leaders.

וכ"כ הרים אתכם על גבי דייניכם.

And so it is written, "He lifted you up above your judges."

The verse hints that the people are, in a sense, "above" their judges and leaders — for it is the merit and readiness of Yisrael that raises those who lead them.

וגם אין רחוק לפרש בפסוק עצמו כן כאשר ירים משה הוא סימן וגבר ישראל.

And it is not far-fetched to explain the verse itself this way: "when Moshe raised [his hand]" is a sign that Yisrael had prevailed.

The verse can even be read in reverse: Moshe's raising of his hands was not the cause but the sign that Yisrael had already prevailed through looking upward.

שע"י שגבר ישראל הרים משה את ידיו.

For because Yisrael prevailed, Moshe raised his hands.

It was Yisrael's spiritual ascent that caused Moshe's hands to rise — the people's readiness lifted their leader's hands.

ובאמת מלחמה זו היה הכנה לכל הדורות.

And in truth this war was a preparation for all the generations.

The battle with Amalek was not a one-time event but a template, establishing a pattern of avodah that would recur throughout all of Jewish history.

וכתיב לשון עתיד ירים יניח.

And it is written in the future tense: "he will raise," "he will let down."

The verse's future-tense verbs ("yarim," "yaniach") hint that this dynamic is ongoing — it speaks not only of that day but of generations yet to come.

כי יש דורות שמתרוממין ידיו של משה וגוברין בנ"י.

For there are generations in which the hands of Moshe are uplifted and Bnei Yisrael prevail.

In some generations the spiritual influence of Moshe — his "hands" — is raised high, and Bnei Yisrael prevail over Amalek through their devotion.

והגם כי הפשוט אמת שהי' עלי' וירידה במלחמה זו ע"י שהי' הכנה לכל הדורות ובזמן שבנ"י מתגברין בתורה זה נק' ירים משה ידו.

And although the plain meaning is true, that there was rising and falling in that war — [the deeper sense is] that because it was a preparation for all the generations, when Bnei Yisrael grow strong in Torah, this is called "Moshe raises his hand."

The literal ups and downs of the battle remain true, but on the deeper level they encode all of history: whenever Bnei Yisrael strengthen themselves in Torah, that is the spiritual reality of "Moshe raising his hand."

ויניח הוא כמ"ש ברפידים שרפו ידיהם מן התורה.

And "he lets down" is as it is said regarding Refidim, that they let their hands grow slack [rafu] from the Torah.

Conversely, "letting the hands down" corresponds to the explanation of "Refidim" as "rafu yadayim" — they slackened their grip on Torah, which is precisely what gives Amalek his opening.

שוב מצאתי מפורש כזה בזוה"ק השייך לפ' תרומה רע"ט ב' ע"ש:

Afterward I found this explicitly stated in the Zohar pertaining to Parshas Terumah, page 279b — see there.

The Sefas Emes notes that he subsequently found this very idea stated openly in the Zohar (Terumah 279b), confirming his interpretation.

Summary: Moshe's raised hands at the battle with Amalek were not themselves the cause of victory but a sign and reflection of Bnei Yisrael's spiritual readiness; when the people turned their hearts upward, his hands were strengthened, and when they slackened from Torah ("Refidim"), his hands fell. Since this battle is a template for all generations, "Moshe raising his hand" represents every era in which Bnei Yisrael strengthen themselves in Torah and so prevail over Amalek — for the leader is uplifted by the very people he leads.
