Kiddush (as Torah study text)
(א) וַיְכֻלּ֛וּ הַשָּׁמַ֥יִם וְהָאָ֖רֶץ וְכָל־צְבָאָֽם׃ (ב) וַיְכַ֤ל אֱלֹהִים֙ בַּיּ֣וֹם הַשְּׁבִיעִ֔י מְלַאכְתּ֖וֹ אֲשֶׁ֣ר עָשָׂ֑ה וַיִּשְׁבֹּת֙ בַּיּ֣וֹם הַשְּׁבִיעִ֔י מִכָּל־מְלַאכְתּ֖וֹ אֲשֶׁ֥ר עָשָֽׂה׃ (ג) וַיְבָ֤רֶךְ אֱלֹהִים֙ אֶת־י֣וֹם הַשְּׁבִיעִ֔י וַיְקַדֵּ֖שׁ אֹת֑וֹ כִּ֣י ב֤וֹ שָׁבַת֙ מִכָּל־מְלַאכְתּ֔וֹ אֲשֶׁר־בָּרָ֥א אֱלֹהִ֖ים לַעֲשֽׂוֹת׃ (פ)

(1) The heaven and the earth were finished, and all their array. (2) On the seventh day God finished the work that God had been doing, and God ceased on the seventh day from all the work that God had done. (3) And God blessed the seventh day and declared it holy, because on it God ceased from all the work of creation that He had done.

Rabbi Alan Ullman: This is not just the first mention of Shabbat in the Torah, it is also the first occurence of the word קדש, holiness. Holiness here––and throughout the Bible–– is defined by the act of stopping. Before we can discover the holiness within our lives, we must first imitate God and stop.

(א) וַיְבָרֶךְ וַיְקַדֵּשׁ והאמת כי הברכה ביום השבת היא מעין הברכות והוא יסוד עולם וַיְקַדֵּשׁ אֹתוֹ כי ימשוך מן הקדש

(1) And he blessed [...] and he sanctified: And the truth is that the blessing on the Shabbat day is the source of blessings and it is the foundation of the world; "and God sanctified it," that it should draw from the holy.

אמר רבא ואיתימא רבי יהושע בן לוי אפילו יחיד המתפלל בערב שבת צריך לומר ויכולו דאמר רב המנונא כל המתפלל בערב שבת ואומר ויכולו מעלה עליו הכתוב כאילו נעשה שותף להקדוש ברוך הוא במעשה בראשית שנאמר ויכולו אל תקרי ויכולו אלא ויכלו אמר רבי אלעזר מניין שהדיבור כמעשה שנאמר בדבר ה׳ שמים נעשו

Rava said, and some say it was Rabbi Yehoshua ben Levi who said: Even an individual who prays on Shabbat evening must recite the passage: “And the heavens and the earth were finished [vaykhullu]” (Genesis 2:1–3), as Rav Hamnuna said: Anyone who prays on Shabbat evening and recites the passage of vaykhullu, the verse ascribed him credit as if he became a partner with the Holy One, Blessed be He, in the act of Creation. As it is stated: “And the heavens and the earth were finished [vaykhullu].” Do not read it as: Were finished [vaykhullu]; rather, as: They finished [vaykhallu]. It is considered as though the Holy One, Blessed be He, and the individual who says this become partners and completed the work together. Rabbi Elazar said: From where is it derived that speech is like action? As it is stated: “By the word of God the heavens were made, and all of their hosts by the breath of His mouth” (Psalms 33:6).

שְׁאִלְתָּא, דְּמִחְיָבִין בֵּית יִשְׂרָאֵל לְמֵינַח בְּיוֹמָא דְשַׁבַּתָּא. דְּכַד בַּרְיֵהּ הַקָּדוֹשׁ בָּרוּךְ הוּא לְעַלְמֵהּ, בַּרְיֵהּ בְּשִׁתָּא יוֹמִין וְנָח בְּיוֹמָא דְשַׁבַּתָּא, בַּרְכֵהּ וְקַדְשֵׁהּ, כְּמָאן דְּבָנָא בֵיתָא וְגָמַר לַעֲבִדְתֵּהּ וַעֲבִיד יוֹמָא טָבָא. כָּךְ אַמְרֵי אֱנָשֵׁי, כִּלּוּל בָּתֵּי, דִּכְתִיב: וַיְכַל אֱלֹהִים בַּיּוֹם הַשְּׁבִיעִי. וְאוֹמֵר רַחֲמָנָא נוּחוּ בְּיוֹמָא דְּשַׁבְּתָא כִּי הֵיכִי דְּנָחֵי בֵּיהּ אֲנָא דִּכְתִיב וַיָּנַח בַּיּוֹם הַשְּׁבִיעִי עַל כֵּן בֵּרַךְ ה' וְגוֹ'.

A Question. Why are the House of Israel required to rest on the Sabbath day? They do so because when the Holy One, blessed be He, created His world, He completed the work of creation in six days and rested on the Sabbath day; He blessed that day and sanctified it, just as one who completes the building of his home commemorates the event with a celebration called a hilul (a ceremony of dedication upon the completion of a home), as it is written: And on the seventh day God finished (va-yikhal) His work (Gen. 2:2). Furthermore, the Merciful One declares: “Rest on the Sabbath day, just as I rested upon it,” as it is said: And He rested on the seventh day, wherefore the Lord blessed the Sabbath day and hallowed it (Exod. 20:11).

(א) ויברך אלהים את יום השביעי כל יום שביעי העתיד ברכו שיהיה יותר מוכן משאר הימים בנפש יתרה לאור באור החיים כאמרם כיון ששבת וינפש אבדה יתרה:

(1) ויברך אלהים את יום השביעי, God blessed every future Shabbat in order that it would be more favorably disposed than the other days to allow the "extra soul” to "bask in the light of life [based on Job 33:30]." As the sages said [see below] concerning שבת וינפש [Exodus 31:17], this refers to the extra soul lost when Shabbat ends.

Abraham Joshua Heschel, The Sabbath

Judaism teaches us to be attached to holiness in time, to be attached to sacred events, to learn how to consecrate sanctuaries that emerge from the magnificent stream of a year. The Sabbaths are our great cathedrals; and our Holy of Holies is a shrine that neither the Romans nor the Germans were able to burn . . . . The meaning of the Sabbath is to celebrate time rather than space. Six days a week we live under the tyranny of things of space; on the Sabbath we try to become attuned to holiness in time. It is a day on which we are called upon to share in what is eternal in time, to turn from the results of creation to the mystery of creation; from the world of creation to the creation of the world.

The Particulars of Rapture: Reflections on Exodus, Avivah Gottlieb Zornberg p. 272: "In kabbalistic imagery, the classic mapping of the world yields six compass points: the four directions, up and down; the seventh point represents the heart of the matter, the nub of the world. As in the relation of the Shabbath to the six days of the week, or of the Shemitta (Sabbatical) year to the six years of agricultural labor, the seventh of the series is the hidden meaning, the truth that cannot be translated into other terms. The elusive origin of God's voice represents the seventh point. Where it is to be found, if not at the heart of the vortex? After all the explorations of desire, there is a return to a still point: "the still point of the turning world. [quoting T.S. Eliot's 'Four Quartets']"

From "Introduction" in How to Be a Shabbes Queen: Supporting Shabbat practice in your community

For six days we try to create a mroe just and compassionate world, and for one we rest our minds, hearts, and bodies from even these most crucial efforts. We conjure up ancient memories and we envision starry futures, in which perhaps all that we are fighting for is present, and we can release into it, and be. We return rejuvenated, and remembering something about why we do the work.

Shabbes for its own sake, a taste of the world to come. For the sake of sharing food and songs and walks and slowness and cuddles and naps, of joy, revelry, and compassion to ourselves. Because it's too easy to forget that this it he point of being alive.

Each week when I light the Shabbes candles, it feels like a gift I am giving myself. Thsi is the part of the blessing of my Shabbes practice being my own choice. A gift of entering into another space, a different relationship to Time, a time-out from value in productivity, that can be hard to take fully without structure for it. Closing the door, as much as is possible, for a day, on capitalism. Opening the door for my second soul to come in and play.

"Radical Shabbat: Free Time, Free People" Arthur Waskow Sojourners, May-June 2000

In short, the Jewish Sabbath is a day for being, not for making. [...] Doing, working, making are not intrinsically evil. Modernity has made possible much that is valuable. But a society that never pauses to catch its breath and reflect on its values, never pauses to love and affirm community and family —such a society forms "making" into a grotesque mockery and turns production, consumption, and overwork into idols.

Eric Fromm, The Sane Society (p.348):

A relatively primitive village in which there are still real feasts, common artistic shared expressions, and no literacy at all – is more advanced culturally and more healthy mentally than our educated, newspaper-reading radio-listening culture.

The Sabbath, Abraham Joshua Heschel, p. xviii

The meaning of the Sabbath is to celebrate time rather than space. Six days a week we live under the tyranny of things of space; on the Sabbath we try to become attuned to holiness in time. It is a day on which we are called upon to share in what is eternal in time, to turn from the results of creation to the mystery of creation; from the world of creation to the creation of the world.

p. 11

The seventh day is like a palace in time with a kingdom for all. It is not a date but an atmosphere. Is it not a different state of consciousness but a different climate; it is as if the appearance of all things somehow changed. The primary awareness is one of our being within the Sabbath rather than of the Sabbath being within us... The difference between the Sabbath and all other days is not to be noticed in the physical structure of things, in their spatial dimension. Things do not change on that day. There is only a difference in the dimension of time, in the relation of the universe to G-d.

The JPS Torah Commentary: Genesis, Nahum M. Sarna at 14: The ascending order of Creation, and the "six-plus-one" literary pattern that determines the presentation of of the narrative, dictates that the seventh day be the momentous climax. Man is indeed the pinnacle of Creation, but central to the cosmogonic drama is the work of God, the solo performer. The account of Creation opened with a statement about God; it will now close with a statement about God. The seventh day is the Lord's Day, through which all the creativity of the preceding days achieves fulfillment. The threefold repetition of the day number indicates its paramount importance within the cosmic whole. The seventh day is in polar contrast to the other six days, which are filled with creative activity. Its distinctive character is the desistance from labor and its infusion with blessing and sanctity. This renders unnecessary the routine approbation formula ["there was evening and there was morning...]. An integral part of the divinely ordained cosmic order, it cannot be abrogated by man. Its blessed and sacred character is a cosmic reality entirely independent of human effort.

The Meaning of Holiness in Judaism, David S. Shapiro at 51: "The Sabbath was the first realm in the created world to be sanctified. "And God blessed the Sabbath day and He hallowed it" (Gen. 2:3). God saw everything that He had made and behold it was very good (ibid. 1:31). He also blessed the creatures that He had fashioned, the fishes, the birds, and human beings, but nothing created was specifically endowed with holiness till the Sabbath arrived. He then hallowed it just as he tendered His blessing to it. From this primordially sanctified segment of time derive all other phases of sanctified time, such as the New Moons, the Festivals, the Day of Atonement, the Sabbatical Year and the Year of Jubilee. All other forms of holiness in the universe are likewise grounded in this original sanctity. On the Sabbath the Space of the universe is sanctified—thus establishing sanctity in Space. The Spirit of man who had been created on the sixth day was likewise sanctified on the Sabbath—thus making possible the sanctity in Spirit."
