Psalms

תהילים קכ״ז:ב׳

Psalms 127:2

The verse declares that God gives sleep to His beloved — 'He grants sleep to those He loves' — suggesting that restful sleep is itself a divine gift and blessing, not merely a biological necessity.

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.

Talmud Bavli, Berakhot

ברכות נ״ז ב

Berakhot 57b

The Talmud lists sleep as one-sixtieth of death, and also one-sixtieth of prophecy — positioning sleep as a liminal state between the mundane and the transcendent, with both physical and spiritual dimensions.

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.

Why it matters — A classic Talmudic teaching that frames sleep as metaphysically significant, touching mortality and divine communication.

Mishneh Torah, De'ot (Human Dispositions)

משנה תורה, הלכות דעות ד׳:ד׳

Mishneh Torah, Human Dispositions 4:4

Rambam prescribes that a person should sleep eight hours each night as part of maintaining a healthy body, which is itself a religious obligation — caring for one's health is framed as service to God.

דַּי לוֹ לָאָדָם לִישֹׁן שְׁלִישָׁן שֶׁהוּא שְׁמוֹנֶה שָׁעוֹת. וְיִהְיוּ בְּסוֹף הַלַּיְלָה כְּדֵי שֶׁתִּהְיֶה מִתְּחִלַּת שְׁנָתוֹ עַד שֶׁתַּעֲלֶה הַשֶּׁמֶשׁ שְׁמוֹנֶה שָׁעוֹת.

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.

Why it matters — Rambam treats adequate sleep as a halakhic and ethical imperative within his framework of bodily stewardship.

Shenei Luchot HaBerit (Shelah HaKadosh)

שני לוחות הברית, שער האותיות, אות ק' קדושה

Shenei Luchot HaBerit, Shaar HaOtiyot, Kedusha 70:1

The Shelah teaches that a person should prepare for sleep with holiness and intention, reciting the bedtime Shema and directing one's final thoughts toward God, so that even sleep becomes an act of worship and the soul ascends during the night.

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.

Toldot Yaakov Yosef

תולדות יעקב יוסף, ויחי

Toldot Yaakov Yosef, Vayechi

R. Yaakov Yosef of Polonne, citing teachings of the Baal Shem Tov, explains that sleep is not a wasted interruption of divine service but a necessary renewal — the descent into unconsciousness allows one to rise with refreshed vitality for Torah and prayer.

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 reframing of sleep as integral to the cycle of spiritual ascent and descent (yeridah letzorech aliyah).
