Tehillim

Psalms 127:2

The verse states that God grants sleep to His beloved, suggesting that restful sleep is a divine gift and sign of trust in God rather than anxious labor.

שָׁ֤וְא לָכֶ֨ם מַשְׁכִּ֪ימֵֽי ק֡וּם מְאַחֲרֵי־שֶׁ֗בֶת אֹ֭כְלֵי לֶ֣חֶם הָעֲצָבִ֑ים כֵּ֤ן יִתֵּ֖ן לִידִיד֣וֹ שֵׁנָֽא׃

In vain do you rise early and stay up late, you who toil for the bread you eat; God’s loved ones are provided for while they sleep.

Why it matters — A foundational biblical text on sleep as a blessing from God, central to any discussion of sleep's spiritual significance.

Talmud Bavli, Berakhot

Berakhot 57b

The Talmud lists sleep as one-sixtieth of death, yet also teaches that sleep restores the body and is a taste of the world to come, reflecting its ambivalent but essential role in human life.

חֲמִשָּׁה וְשִׁשָּׁה וַעֲשָׂרָה סִימָן: חֲמִשָּׁה אֶחָד מִשִּׁשִּׁים, אֵלּוּ הֵן: אֵשׁ, דְּבַשׁ, וְשַׁבָּת, וְשֵׁינָה, וַחֲלוֹם. אֵשׁ — אֶחָד מִשִּׁשִּׁים לְגֵיהִנָּם. דְּבַשׁ — אֶחָד מִשִּׁשִּׁים לַמָּן. שַׁבָּת — אֶחָד מִשִּׁשִּׁים לָעוֹלָם הַבָּא. שֵׁינָה — אֶחָד מִשִּׁשִּׁים לַמִּיתָה. חֲלוֹם — אֶחָד מִשִּׁשִּׁים לַנְּבוּאָה. שִׁשָּׁה דְּבָרִים סִימָן יָפֶה לַחוֹלֶה, אֵלּוּ הֵן: עִטּוּשׁ, זֵיעָה, שִׁלְשׁוּל, קֶרִי, וְשֵׁינָה, וַחֲלוֹם. עִטּוּשׁ — דִּכְתִיב: ״עֲטִישׁוֹתָיו תָּהֵל אוֹר״. זֵיעָה — דִּכְתִיב: ״בְּזֵעַת אַפֶּיךָ תֹּאכַל לֶחֶם״. שִׁלְשׁוּל — דִּכְתִיב: ״מִהַר צֹעֶה לְהִפָּתֵחַ וְלֹא יָמוּת לַשַּׁחַת״. קֶרִי — דִּכְתִיב: ״יִרְאֶה זֶרַע יַאֲרִיךְ יָמִים״. שֵׁינָה — דִּכְתִיב: ״יָשַׁנְתִּי אָז יָנוּחַ לִי״. חֲלוֹם — דִּכְתִיב: ״וְתַחֲלִימֵנִי וְהַחֲיֵנִי״.

The numbers five, six, and ten are mnemonics for the categories to follow. The Gemara says: There are five matters in our world which are one-sixtieth of their most extreme manifestations. They are: Fire, honey, Shabbat, sleep, and a dream. The Gemara elaborates: Our fire is one-sixtieth of the fire of Gehenna; honey is one-sixtieth of manna; Shabbat is one-sixtieth of the World-to-Come; sleep is one-sixtieth of death; and a dream is one-sixtieth of prophecy. Similarly: Six matters are good omens for the sick: Sneezing, sweating, diarrhea, a seminal emission, sleep, and a dream. These are all alluded to in Scripture: Sneezing, as it is written: “His sneezes flash forth light” (Job 41:10), indicating that by means of a sneeze one comes to see the light of the world. Sweat, as it is written: “In the sweat of your face shall you eat bread” (Genesis 3:19). Diarrhea, as it is written: “He that is bent down shall speedily be loosed; and he shall not go down dying into the pit” (Isaiah 51:14). A seminal emission, as it is written: “That he might see his seed, prolong his days” (Isaiah 53:10). Sleep, as it is written: “I should have slept; then had I been at rest” (Job 3:13). A dream, as it is written: “Wherefore You recover me [vataḥalimeni], and make me to live” (Isaiah 38:16); vataḥalimeni is interpreted as etymologically similar to ḥalom, dream.

Rambam, Hilkhot De'ot

Mishneh Torah, Human Dispositions 4:4

The Rambam prescribes that a person should sleep eight hours per night, at the end of the night, so the body is fully rested and the mind is alert for Torah study and work.

דַּי לוֹ לָאָדָם לִישֹׁן שְׁלִישָׁן שֶׁהוּא שְׁמוֹנֶה שָׁעוֹת. וְיִהְיוּ בְּסוֹף הַלַּיְלָה כְּדֵי שֶׁתִּהְיֶה מִתְּחִלַּת שְׁנָתוֹ עַד שֶׁתַּעֲלֶה הַשֶּׁמֶשׁ שְׁמוֹנֶה שָׁעוֹת. וְנִמְצָא עוֹמֵד מִמִּטָּתוֹ קֹדֶם שֶׁתַּעֲלֶה הַשֶּׁמֶשׁ:

It is sufficient for a man to sleep a third of this period; i.e., eight hours. These should be towards the end of the night, so that there be eight hours from the beginning of his sleep until sunrise. Thus, he should rise from his bed before sunrise.

Why it matters — The Rambam integrates sleep into his broader system of health and character development, treating adequate sleep as a religious and ethical obligation.

Shelah HaKadosh, Shnei Luchot HaBrit

Shenei Luchot HaBerit, Shaar HaOtiyot, Kedusha

The Shelah teaches that one should sanctify the act of going to sleep with intention and prayer, reciting the Shema and entrusting one's soul to God, transforming sleep from a mundane necessity into an act of holiness.

ויברא אלהים את האדם בצלמו (בראשית א, כז), בצלם אלהים עשה את האדם (שם ט, ו). הכוונה אף על תכונת הגוף ואבריו וגידיו וכל אשר בו, הכל רמזים עליונים, על כן נפח בו נשמת חיים. ואם באתי לפרש זה, לא יספיק כמה וכמה קונטריסים לפרש אפילו אחד מאלף ממה שרמוז בספר הזוהר באידרא רבה ובאידרא זוטרא וביתר המקומות.

Why it matters — An Acharon source that elevates sleep into a spiritual practice requiring conscious preparation and intention.

Toldot Yaakov Yosef

Toldot Yaakov Yosef, Vayechi

The Toldot Yaakov Yosef, drawing on Baal Shem Tov teachings, explains that during sleep the soul ascends and receives spiritual nourishment, so that waking is a form of renewal and rebirth of divine energy within the person.

והנה הרב בעללות אפרים (מאמר קמא) כתב, כי מדת הסתפקות גם כשמונח על הארץ הוא ישן מיד, מה שאין כן באחרים וכו'. וכיוצא בזה שמעתי, אמת משל היה, בעשיר אחד מליטא, שהי' הולך בדרך עם סוחרי מדינתינו, ובמלון הם הציעו כרים וכסתות, והוא הי' מונח בארץ לישן, רק המרדעת תחת ראשו, והי' ישן מיד, מה שאין כן הם. ושאלו פיו מהו זה, והשיב כי מה שיש לו הוא שלו ומניח לו לישן, מה שאין כן הם מה שיש להם אינו שלהם וכו', ודפח"ח.

Why it matters — A Hasidic source that reframes sleep as a spiritually active state of soul-ascent and divine connection rather than mere physical rest.
