Prostration as a Jewish Spiritual Practice "וְֽ֭הִשְׁתַּחֲווּ"

"Prostration is the placement of the body in a reverentially or submissively prone position as a gesture. Typically prostration is distinguished from the lesser acts of bowing or kneeling by involving a part of the body above the knee touching the ground, especially the hands."

בראשית י״ז:ב׳-ג׳

(ב) וְאֶתְּנָ֥ה בְרִיתִ֖י בֵּינִ֣י וּבֵינֶ֑ךָ וְאַרְבֶּ֥ה אוֹתְךָ֖ בִּמְאֹ֥ד מְאֹֽד׃ (ג) וַיִּפֹּ֥ל אַבְרָ֖ם עַל־פָּנָ֑יו

Genesis 17:2-3

(2) I will establish My covenant between Me and you, and I will make you exceedingly numerous.” (3) Abram threw himself on his face [prostrated himself].

שמות י״ב:כ״ז

(כז) וַאֲמַרְתֶּ֡ם זֶֽבַח־פֶּ֨סַח ה֜וּא לַֽה' אֲשֶׁ֣ר פָּ֠סַח עַל־בָּתֵּ֤י בְנֵֽי־יִשְׂרָאֵל֙ בְּמִצְרַ֔יִם בְּנָגְפּ֥וֹ אֶת־מִצְרַ֖יִם וְאֶת־בָּתֵּ֣ינוּ הִצִּ֑יל וַיִּקֹּ֥ד הָעָ֖ם וַיִּֽשְׁתַּחֲוּֽוּ׃

Exodus 12:27

(27) you shall say, ‘It is the passover sacrifice to the LORD, because He passed over the houses of the Israelites in Egypt when He smote the Egyptians, but saved our houses.’” The people then prostrated.

שמות כ׳:ה׳

(ה) לֹֽא־תִשְׁתַּחְוֶ֥֣ה לָהֶ֖ם֮ וְלֹ֣א תָעָבְדֵ֑ם֒ כִּ֣י אָֽנֹכִ֞י ה' אֱלֹקֶ֙יךָ֙ אֵ֣ל קַנָּ֔א׃

Exodus 20:5

(5) You shall not bow down to them or serve them. For I the LORD your God am a jealous God

רות ב׳:י׳

וַתִּפֹּל֙ עַל־פָּנֶ֔יהָ וַתִּשְׁתַּ֖חוּ אָ֑רְצָה וַתֹּ֣אמֶר אֵלָ֗יו מַדּוּעַ֩ מָצָ֨אתִי חֵ֤ן בְּעֵינֶ֙יךָ֙ לְהַכִּירֵ֔נִי וְאָּנֹכִ֖י נָכְרִיָּֽה׃

Ruth 2:10

She prostrated herself with her face to the ground, and said to him, “Why are you so kind as to single me out, when I am a foreigner?”

מגילה כ״ב ב:ט״ז

תנו רבנן קידה על אפים שנאמר (מלכים א א, לא) ותקד בת שבע אפים ארץ כריעה על ברכים וכן הוא אומר (מלכים א ח, נד) מכרוע על ברכיו השתחואה זו פישוט ידים ורגלים שנאמר (בראשית לז, י) הבוא נבוא אני ואמך ואחיך להשתחות לך ארצה

Megillah 22b:16

Apropos Rav’s practice of prostrating himself, the Gemara continues with a discussion of different forms of bowing. The Sages taught in a baraita: The term kidda indicates falling upon one’s face, with one’s face toward the ground, as it is stated: “Then Bathsheba bowed [vatikod] with her face to the ground” (I Kings 1:31). Keria means bowing upon one’s knees, as it is stated with regard to Solomon: He finished praying and “he rose from before the altar of the Lord, from kneeling [mikkeroa] upon his knees” (I Kings 8:54). Finally, hishtaḥava’a, that is bowing with one’s arms and legs spread in total submission, as it is stated that Jacob asked, in response to Joseph’s dream: “Shall I and your mother and your brothers indeed come to bow down [lehishtaḥavot] to you to the ground?” (Genesis 37:10).

בראשית רבה נ״ו:ב׳

אָמַר רַבִּי יִצְחָק הַכֹּל בִּזְכוּת הִשְׁתַּחֲוָיָה, וְאַבְרָהָם לֹא חָזַר מֵהַר הַמּוֹרִיָּה בְּשָׁלוֹם אֶלָּא בִּזְכוּת הִשְׁתַּחֲוָיָה, וְנִשְׁתַּחֲוֶה וְנָשׁוּבָה אֲלֵיכֶם. יִשְׂרָאֵל לֹא נִגְאֲלוּ אֶלָּא בִּזְכוּת הִשְׁתַּחֲוָיָה, שֶׁנֶּאֱמַר (שמות ד, לא): וַיַּאֲמֵן הָעָם וגו' וַיִקְדּוּ וַיִּשְׁתַּחֲווּ. הַתּוֹרָה לֹא נִתְּנָה אֶלָּא בִּזְכוּת הִשְׁתַּחֲוָיָה, שֶׁנֶּאֱמַר (שמות כד, א): וְהִשְׁתַּחֲוִיתֶם מֵרָחֹק. חַנָּה לֹא נִפְקְדָה אֶלָּא בִּזְכוּת הִשְׁתַּחֲוָיָה, שֶׁנֶּאֱמַר (שמואל א א, כח): וַיִּשְׁתַּחוּ שָׁם לַה': הַגָּלֻיּוֹת אֵינָן מִתְכַּנְסוֹת אֶלָּא בִּזְכוּת הִשְׁתַּחֲוָיָה, שֶׁנֶּאֱמַר (ישעיה כז, יג): וְהָיָה בַּיּוֹם הַהוּא יִתָּקַע בְּשׁוֹפָר גָּדוֹל וגו' וְהִשְׁתַּחֲווּ לַה' בְּהַר הַקֹּדֶשׁ בִּירוּשָׁלַיִם. בֵּית הַמִּקְדָּשׁ לֹא נִבְנָה אֶלָּא בִּזְכוּת הִשְׁתַּחֲוָיָה, שֶׁנֶּאֱמַר (תהלים צט, ט): רוֹמְמוּ ה' אֱלֹהֵינוּ וְהִשְׁתַּחֲווּ לְהַר קָדְשׁוֹ. הַמֵּתִים אֵינָן חַיִּין אֶלָּא בִּזְכוּת הִשְׁתַּחֲוָיָה, שֶׁנֶּאֱמַר (תהלים צה, ו): בֹּאוּ נִשְׁתַּחֲוֶה וְנִכְרָעָה נִבְרְכָה לִפְנֵי ה' עֹשֵׂנוּ.

Bereshit Rabbah 56:2

Rabbi Itzchak said: Everything happened as a reward for prostrating.

Abraham returned in peace from Mount Moriah only as a reward for prostrating. “And we will prostrate, and we will come back to you.” Israel were redeemed only as a reward for prostrating: “And the people believed...then they bowed their heads and prostrated” (Ex. 4:31). The Torah was given only as a reward for prostrating: “And prostrate y’all afar off” (Ex. 24:1). Hannah was remembered only as a reward for prostrating: “And they prostrated before God” (I Sam. 1:19). The exiles will be reassembled only as a reward for prostrating: “And it shall come to pass in that day, that a great horn shall be blown; and they shall come that were lost..and that were dispersed.. and they shall prostrate to God in the holy mountain at Jerusalem” (Isa. 27:13). The Temple was built only as a reward for prostrating: “Exalt y’all Ad-nai our God, and prostrate at God's holy mountain” (Ps. 99:9). The dead will come to life again only as a reward for prostrating: “O come, let us worship and bend the knee; let us kneel before Ad-nai our Maker (Ps 95:6).

ברכות כ״ח ב:י״ח

וְאָמַר רַבִּי תַּנְחוּם אָמַר רַבִּי יְהוֹשֻׁעַ בֶּן לֵוִי: הַמִּתְפַּלֵּל צָרִיךְ שֶׁיִּכְרַע עַד שֶׁיִּתְפַּקְּקוּ כׇּל חוּלְיוֹת שֶׁבַּשִּׁדְרָה.

Berakhot 28b:18

Since Rabbi Yehoshua ben Levi’s opinion based the Amida prayer on the spinal vertebrae, the Gemara cites another statement of his that connects the two: Rabbi Tanḥum said that Rabbi Yehoshua ben Levi said: In those blessings where one is required to bow, one who prays must bow until all the vertebrae in the spine protrude.

כְּרִיעָה כֵּיצַד. הַמִּתְפַּלֵּל כּוֹרֵעַ חָמֵשׁ כְּרִיעוֹת בְּכָל תְּפִלָּה וּתְפִלָּה. בִּבְרָכָה רִאשׁוֹנָה בַּתְּחִלָּה וּבַסּוֹף. וּבְהוֹדָיָה בַּתְּחִלָּה וּבַסּוֹף. וּכְשֶׁגּוֹמֵר הַתְּפִלָּה כּוֹרֵעַ וּפוֹסֵעַ שָׁלֹשׁ פְּסִיעוֹת לַאֲחוֹרָיו. וּכְשֶׁהוּא כּוֹרֵעַ נוֹתֵן שָׁלוֹם מִשְּׂמֹאל עַצְמוֹ וְאַחַר כָּךְ מִימִין עַצְמוֹ וְאַחַר כָּךְ מַגְבִּיהַּ רֹאשׁוֹ מִן הַכְּרִיעָה. וּכְשֶׁהוּא כּוֹרֵעַ בְּאַרְבַּע הַכְּרִיעוֹת כּוֹרֵעַ בְּבָרוּךְ וּכְשֶׁהוּא זוֹקֵף זוֹקֵף בַּשֵּׁם. בַּמֶּה דְּבָרִים אֲמוּרִים בְּהֶדְיוֹט. אֲבָל כֹּהֵן גָּדוֹל כּוֹרֵעַ בִּתְחִלַּת כָּל בְּרָכָה וּבְסוֹף כָּל בְּרָכָה. וְהַמֶּלֶךְ כֵּיוָן שֶׁשָּׁחָה בָּרִאשׁוֹנָה אֵינוֹ מַגְבִּיהַּ רֹאשׁוֹ עַד שֶׁגּוֹמֵר כָּל תְּפִלָּתוֹ:

Rambam, Hilkhot Tefillah 5:10

Bowing: What is implied? One praying bows five times in each and every Amidah: In the first blessing, at the beginning and at the end; in the blessing of thanks, at the beginning and at the end; and upon completing the Amidah, one bows and takes three steps backwards while bowing. She takes leave from her left and afterwards, from her right. Then, she lifts her head up from the bowed position. When she bows the [other] four times, she does so at [the utterance of the word] "Blessed" and straightens up when [reciting] God's name. To whom does the above apply? To an average person. However, the High Priest bows at the beginning and end of each and every blessing. A queen bows at the beginning [of the Amidah] and does not lift her head until she completes her whole Amidah.
