Devarim – Shamor et Yom HaShabbat

דברים ה׳:י״ב

Deuteronomy 5:12

The fourth commandment as given in Deuteronomy uses the word 'Shamor' (guard/observe) — 'Shamor et yom haShabbat lekadsho' — as opposed to 'Zachor' in Exodus, establishing the dual dimension of Shabbat observance.

שָׁמ֛֣וֹר אֶת־י֥וֹם֩ הַשַּׁבָּ֖֨ת לְקַדְּשׁ֑֜וֹ כַּאֲשֶׁ֥ר צִוְּךָ֖֣ ׀ יְהֹוָ֥֣ה אֱלֹהֶֽ֗יךָ׃

Observe the sabbath day and keep it holy, as the ETERNAL your God has commanded you.

Mishnah Berakhot – Women and Time-Bound Commandments

משנה ברכות ג׳:ג׳

Mishnah Berakhot 3:3

The Mishnah discusses which positive time-bound commandments women are exempt from, a discussion directly relevant to whether women are obligated in Shamor (the prohibitive dimension of Shabbat) vs. Zachor.

נָשִׁים וַעֲבָדִים וּקְטַנִּים פְּטוּרִין מִקְּרִיאַת שְׁמַע וּמִן הַתְּפִלִּין, וְחַיָּבִין בִּתְפִלָּה וּבִמְזוּזָה, וּבְבִרְכַּת הַמָּזוֹן:

Kuzari – Shabbat as the Pillar of Jewish Faith

הכוזרי ב׳:נ׳

Kuzari 2:50

Rabbi Yehuda HaLevi argues that the observance of Shabbat — guarding it — is the most visible and defining marker of Jewish peoplehood, a living testimony to the divine act of Creation that no other nation can claim.

וְהָיְתָה שְׁמִירַת הַשַּׁבָּת הִיא בְעַצְמָהּ הַהוֹדָאָה בָאֱלֹהוּת, אֲבָל –כְּאִלּוּ הִיא הוֹדָאָה בְדִבּוּר מַעֲשִׂי, כִּי מִי שֶׁמְּקַבֵּל מִצְוַת שַׁבָּת בַּעֲבוּר שֶׁבָּהּ הָיָה כְלוֹת מַעֲשֵׂה בְרֵאשִׁית, כְּבָר הוֹדָה בַּחִדּוּשׁ מִבְּלִי סָפֵק, וּמִי שֶׁהוֹדָה בַּחִדּוּשׁ הוֹדָה בַמְחַדֵּשׁ הָעוֹשֶׂה יִתְבָּרָךְ. וּמִי שֶׁלֹּא קִבְּלָהּ יִפֹּל בִּסְפֵקוֹת הַקַּדְמוּת וְלֹא תִזַּךְ אֱמוּנָתוֹ לְבוֹרֵא הָעוֹלָם. אִם כֵּן שְׁמִירַת מִצְווֹת הַשַּׁבָּת מְקָרֶבֶת אֶל הַבּוֹרֵא יוֹתֵר מֵהַפְּרִישׁוּת וְהַנְּזִירוּת.

The observance of the Sabbath is itself an acknowledgment of His omnipotence, and at the same time an acknowledgment of the creation by the divine word. He who observes the Sabbath because the work of creation was finished on it acknowledges the creation itself. He who believes in the creation believes in the Creator. He, however, who does not believe in it falls a prey to doubts of God's eternity and to doubts of the existence of the world's Creator.

Rambam – Hilkhot Shabbat, the Two Commandments

משנה תורה, הלכות שבת א׳:א׳-ב׳

Mishneh Torah, Sabbath 1:1-2

Rambam codifies both the positive commandment of Zachor and the negative commandment of Shamor as the two Torah-level obligations of Shabbat — to sanctify it in speech and to refrain from forbidden labor.

שְׁבִיתָה בַּשְּׁבִיעִי מִמְּלָאכָה מִצְוַת עֲשֵׂה שֶׁנֶּאֱמַר (שמות לד כא) "וּבַיּוֹם הַשְּׁבִיעִי תִּשְׁבֹּת". וְכָל הָעוֹשֶׂה בּוֹ מְלָאכָה בִּטֵּל מִצְוַת עֲשֵׂה וְעָבַר עַל לֹא תַּעֲשֶׂה שֶׁנֶּאֱמַר (דברים ה יד) "לֹא תַעֲשֶׂה כָל מְלָאכָה". וּמַה הוּא חַיָּב עַל עֲשִׂיַּת מְלָאכָה. אִם עָשָׂה בִּרְצוֹנוֹ בְּזָדוֹן חַיָּב כָּרֵת. וְאִם הָיוּ שָׁם עֵדִים וְהַתְרָאָה נִסְקָל. וְאִם עָשָׂה בִּשְׁגָגָה חַיָּב קָרְבַּן חַטָּאת קְבוּעָה:

Resting from labor on the seventh day fulfills a positive commandment, as [Exodus 23:12] states, "And you shall rest on the seventh day." Anyone who performs a labor on this day negates the observance of a positive commandment and also transgresses a negative commandment, for [ibid. 20:10] states, "Do not perform any labor [on it]." What are the liabilities incurred by a person who performs labor [on this day]? If he does so willingly, as a conscious act of defiance, he is liable for karet; if witnesses who administer a warning are present, he should be stoned [to death]. If he performs [labor] without being conscious of the transgression, he is liable to bring a sin offering of a fixed nature.

Tomer Devorah – Shamor as Imitatio Dei

תומר דבורה א׳:א׳

Tomer Devorah 1:1

R. Moshe Cordovero connects the attribute of guarding (shmirah) to the divine Sefirah of Malkhut, teaching that just as God 'guards' Israel, a person fulfills Shamor by emulating divine watchfulness and protecting sacred time.

הָאָדָם רָאוּי שֶׁיִּתְדַּמֶּה לְקוֹנוֹ וְאָז יִהְיֶה בְּסוֹד הַצּוּרָה הָעֶלְיוֹנָה צֶלֶם וּדְמוּת, שֶׁאִלּוּ יְדֻמֶּה בְּגוּפוֹ וְלֹא בִּפְעֻלּוֹת הֲרֵי הוּא מַכְזִיב הַצּוּרָה וְיֹאמְרוּ עָלָיו צוּרָה נָאָה וּמַעֲשִׂים כְּעוּרִים. שֶׁהֲרֵי עִיקָר הַצֶּלֶם וְהַדְּמוּת הָעֶלְיוֹן הֵן פְּעֻלּוֹתָיו, וּמַה יוֹעִיל לוֹ הֱיוֹתוֹ כְּצוּרָה הָעֶלְיוֹנָה דְּמוּת תַּבְנִית אֵבָרָיו וּבַפְּעֻלּוֹת לֹא יִתְדַמֶּה לְקוֹנוֹ.

Chapter 1 - That it is fitting for a person to resemble his Creator: It is fitting for a person to resemble his Creator and then he will be [configured] in the secret of the Highest Form, [both] in image and likeness. As if he is alike in his body but not in his actions, he betrays the Form; and they will say about him, "A lovely form, but ugly deeds." As behold, the essence of the Highest Image and Likeness is His actions.

Shulchan Arukh – Honoring Shabbat (Shamor in Practice)

שולחן ערוך, אורח חיים רמ״ב:א׳

Shulchan Arukh, Orach Chayim 242:1

The Shulchan Arukh rules on the practical fulfillment of Shamor — guarding Shabbat by avoiding melacha — and the obligation to honor it through preparation beforehand, integrating the active and passive dimensions of the commandment.

אפילו מי שצריך לאחרים אם יש לו מעט משלו צריך לזרז עצמו לכבד את השבת ולא אמרו עשה שבתך חול ולא תצטרך לבריות אלא למי שהשעה דחוקה לו ביותר על כן צריך לצמצם בשאר ימים כדי לכבד את השבת מתקנת עזרא שיהיו מכבסים בגדים בחמישי בשבת מפני כבוד השבת:

Mesillat Yesharim – Zehirut as the Practice of Shamor

מסילת ישרים ב׳

Mesillat Yesharim 2

R. Moshe Chaim Luzzatto opens Mesillat Yesharim with the quality of Zehirut (watchfulness/guarding), which is functionally the ethical and spiritual equivalent of Shamor — constant vigilance against transgression and the guarding of one's actions.

בְּבֵאוּר מִדַּת הַזְּהִירוּת הִנֵּה עִנְיַן הַזְּהִירוּת הוּא שֶׁיִּהְיֶה הָאָדָם נִזְהָר בְּמַעֲשָׂיו וּבְעִנְיָנָיו, כְּלוֹמַר, מִתְבּוֹנֵן וּמְפַקֵּחַ עַל מַעֲשָׂיו וּדְרָכָיו, הֲטוֹבִים הֵם אִם לֹא, לְבִלְתִּי עֲזֹב נַפְשׁוֹ לְסַכָּנַת הָאֲבַדּוֹן חָס וְשָׁלוֹם וְלֹא יֵלֵךְ בְּמַהֲלַךְ הֶרְגֵּלוֹ כְּעִוֵּר בַּאֲפֵלָה. וְהִנֵּה זֶה דָּבָר שֶׁהַשֵּׂכֶל יְחַיְּבֵהוּ וַדַּאי. כִּי אַחֲרֵי שֶׁיֵּשׁ לָאָדָם דֵּעָה וְהַשְׂכֵּל לְהַצִּיל אֶת עַצְמוֹ וְלִבְרֹחַ מֵאֲבַדּוֹן נִשְׁמָתוֹ, אֵיךְ יִתָּכֵן שֶׁיִּרְצֶה לְהַעֲלִים עֵינָיו מֵהַצָּלָתוֹ,

The idea of watchfulness is for one to be cautious of his deeds and matters, namely, contemplating and watching over his deeds and ways whether they are good or evil; not abandoning his soul to the danger of destruction, G-d forbid, and not walking through the course of habit like a blind man in darkness. Reason certainly obligates this. For after a person has knowledge and reason to save himself and escape from the destruction of his soul, how is it conceivable that he would willingly blind his eyes from saving himself?!

Noam Elimelekh – Shamor and the Tzaddik's Role

R. Elimelekh of Lizhensk teaches that the tzaddik acts as the guardian (shomer) of Israel, linking the concept of Shamor to the Shabbat's protective spiritual force that shields the community from harmful influences throughout the week.

ויעקב היה רועה את צאן לבן הנותרות, נ"ל לפרש ד"לבן" רמז ללובן העליון ו"צאן" רמז לישראל צאן קדשים, ויעקב אבינו ע"ה היה רוצה לתקן לישראל בגלות המר והמתיק הדינים מעליהם, וזהו ה"נותרות" רמז לגלות המר שאנחנו נותרנו מעט מהרבה, וזהו "רועה את צאן" היינו ישראל הנותרים בגלות המר היה רועה אותן, וממתיק הדינים מהם לרחמים.

Kedushat Levi – Zachor and Shamor as Love and Awe

קדושת לוי, שמות, יתרו

Kedushat Levi, Exodus, Yitro

R. Levi Yitzchak of Berditchev interprets Zachor as the dimension of love (ahavah) and Shamor as the dimension of awe (yirah), teaching that authentic Shabbat observance requires both emotional stances toward the Divine.

והנה כתיב (תהלים קכה, ב) ירושלים הרים סביב לה וה' סביב לעמו, דירושלים הוא כנסת ישראל ששם נכללו כל הדברים והוא מסובב מן ההרים ואין הרים אלא אבות, ששרשי הקדושה ברוחניות בעולמות העליונים מסבבים הכנסת ישראל וכל אחד מישראל צריך שיהיה דבוק בהשורש ויהיה השורש מאיר להענף בלי שום מסך ובלי שום תערובת רע חס ושלום. וכל אדם צריך לדבק במידותיו הקדושים וצריך האדם להיות עושה חסד בעולם. אך העיקר שיהא החסדים טובים שהם החסדים מן השורש חסד עליון ולא יהיה בו חלק רע, כי אף על פי שהחסד הוא טוב מכל מקום לא יהיה מעורב בו רע כמו שאמרו חכמינו ז"ל (קהלת רבה ז) כל הנעשה רחמן על האכזרים וכו', וצריך להיות החסד כולו טוב. וכמו כן הגבורות מה שצריך האדם להתגבר על יצרו ולהכניע כל חלק הרע לשעבד תחת הטוב ואז כשבא האדם לעבודה אמיתית ומדבק את עצמו בשורש האמת ששם כלול כל הגוונין ואדם צריך להתדבק בכל המדות בחסד וגבורה שלו ורחמנות שלו כשהוא באמת ואז הוא כלול מג' קווין, כי במדת האמת כלול הכל. וזה בחינת שי"ן הכלול מג' קווין. וזהו בחודש השלישי, שהוא בחינת האמת שהוא השי"ן שהוא משולש מחסד וגבורה והתפארת כשאדם מגיע לבחינת האמת אז הוא יוצא מכל חלקי הרע ומכל המצירים.

aware of the slight variation in the text from ‎our verse, Moses reassures the people that this is not a deviation. ‎Ed.]‎ ‎[Most students in elementary school are already familiar ‎with the line in the hymn of ‎לכה דודי‎ that ‎שמור וזכור בדבור אחד ‏השמיענו א-ל המיוחד‎ “shamor and zachor the One and ‎only G’d has let us hear as a single word.” Ed.] The source ‎of the words in the hymn are found already in the Talmud Rosh ‎Hashanah 27. The deeper meaning of this somewhat enigmatic ‎statement is that the commandments of the Torah may be ‎divided into two parts; 1) the actual physical performance of the ‎commandment; 2) awareness at the time of performance of the ‎underlying intention of the Creator when He gave us this ‎commandment.. The qualitative difference between these two ‎aspects of the commandment is that only the performance is of ‎the essence, the underlying intention of G’d when formulating ‎the commandment is secondary.‎ There is, however an exception to this rule, and this ‎exception is the commandment of keeping the Sabbath holy.

recovered from “Tanya, Iggeret HaKodesh 15

Tanya – Shmirah and the Guarding of the Soul

תניא, אגרת הקדש ט״ו

Tanya, Part IV; Iggeret HaKodesh 15

The Alter Rebbe discusses how the divine energy of Shabbat serves as a shmirah (protection) for the soul's divine light, connecting the concept of guarding (shamor) to the inner spiritual architecture of the Jewish soul across the week.

וְעַל כֵּן, גַּם בְּנִשְׁמַת הָאָדָם מֵאִיר אוֹר־אֵין־סוֹף בָּרוּךְ־הוּא, מְלוּבָּשׁ וְגָנוּז בְּאוֹר הַחָכְמָה שֶׁבָּהּ, לְהַחֲיוֹת אֶת הָאָדָם. וּמִמֶּנָּה יוּכַל הָאָדָם לְהָבִין קְצָת בִּסְפִירוֹת הָעֶלְיוֹנוֹת, שֶׁכּוּלָּן מְאִירוֹת בְּנִשְׁמָתוֹ הַכְּלוּלָה מֵהֶן.

Thus it follows that the light of the En Sof, blessed is He, radiates in the soul (neshamah) of man as well, vested and concealed in the light of its chochmah in order to animate man. And from (the soul) man is able to understand somewhat of the supernal sefirot, for they all radiate in his soul—which compounds them.
