Leviathan Enemy of God
(א) בַּיּ֣וֹם הַה֡וּא יִפְקֹ֣ד ה' בְּחַרְב֨וֹ הַקָּשָׁ֜ה וְהַגְּדוֹלָ֣ה וְהַֽחֲזָקָ֗ה עַ֤ל לִוְיָתָן֙ נָחָ֣שׁ בָּרִ֔חַ וְעַל֙ לִוְיָתָ֔ן נָחָ֖שׁ עֲקַלָּת֑וֹן וְהָרַ֥ג אֶת־הַתַּנִּ֖ין אֲשֶׁ֥ר בַּיָּֽם׃ (ס)
(1) In that day the LORD will punish, With His great, cruel, mighty sword Leviathan the Elusive Serpent— Leviathan the Twisting Serpent; He will slay the Dragon of the sea.
(יג) אַתָּ֤ה פוֹרַ֣רְתָּ בְעָזְּךָ֣ יָ֑ם שִׁבַּ֖רְתָּ רָאשֵׁ֥י תַ֝נִּינִ֗ים עַל־הַמָּֽיִם׃ (יד) אַתָּ֣ה רִ֭צַּצְתָּ רָאשֵׁ֣י לִוְיָתָ֑ן תִּתְּנֶ֥נּוּ מַ֝אֲכָ֗ל לְעָ֣ם לְצִיִּֽים׃
(13) it was You who drove back the sea with Your might, who smashed the heads of the monsters in the waters; (14) it was You who crushed the heads of Leviathan, who left him as food for the denizens of the desert;
(כו) שָׁ֭ם אֳנִיּ֣וֹת יְהַלֵּכ֑וּן לִ֝וְיָתָ֗ן זֶֽה־יָצַ֥רְתָּ לְשַֽׂחֶק־בּֽוֹ׃
(26) There go the ships, and Leviathan that You formed to sport with.
(ב) וּלְמַ֡עַן תְּסַפֵּר֩ בְּאָזְנֵ֨י בִנְךָ֜ וּבֶן־בִּנְךָ֗ אֵ֣ת אֲשֶׁ֤ר הִתְעַלַּ֙לְתִּי֙ בְּמִצְרַ֔יִם וְאֶת־אֹתֹתַ֖י אֲשֶׁר־שַׂ֣מְתִּי בָ֑ם וִֽידַעְתֶּ֖ם כִּי־אֲנִ֥י ה'׃
(2) and that you may recount in the hearing of your sons and of your sons’ sons how I made a mockery of the Egyptians and how I displayed My signs among them—in order that you may know that I am the LORD.”
(ג) דַּבֵּ֨ר וְאָמַרְתָּ֜ כֹּֽה־אָמַ֣ר ׀ אדושם ה' הִנְנִ֤י עָלֶ֙יךָ֙ פַּרְעֹ֣ה מֶֽלֶךְ־מִצְרַ֔יִם הַתַּנִּים֙ הַגָּד֔וֹל הָרֹבֵ֖ץ בְּת֣וֹךְ יְאֹרָ֑יו אֲשֶׁ֥ר אָמַ֛ר לִ֥י יְאֹרִ֖י וַאֲנִ֥י עֲשִׂיתִֽנִי׃
(3) Speak these words: Thus said the Lord GOD: I am going to deal with you, O Pharaoh king of Egypt, Mighty monster, sprawling in your channels, Who said, My Nile is my own; I made it for myself.

(25) Can you draw out Leviathan by a fishhook? Can you press down his tongue by a rope? (26) Can you put a ring through his nose, Or pierce his jaw with a barb? (27) Will he plead with you at length? Will he speak soft words to you? (28) Will he make an agreement with you To be taken as your lifelong slave? (29) Will you play with him like a bird, And tie him down for your girls? (30) Shall traders traffic in him? Will he be divided up among merchants? (31) Can you fill his skin with darts Or his head with fish-spears? (32) Lay a hand on him, And you will never think of battle again. (1) See, any hope [of capturing] him must be disappointed; One is prostrated by the very sight of him. (2) There is no one so fierce as to rouse him; Who then can stand up to Me? (3) Whoever confronts Me I will requite, For everything under the heavens is Mine. (4) I will not be silent concerning him Or the praise of his martial exploits. (5) Who can uncover his outer garment? Who can penetrate the folds of his jowls? (6) Who can pry open the doors of his face? His bared teeth strike terror. (7) His protective scales are his pride, Locked with a binding seal. (8) One scale touches the other; Not even a breath can enter between them. (9) Each clings to each; They are interlocked so they cannot be parted. (10) His sneezings flash lightning, And his eyes are like the glimmerings of dawn. (11) Firebrands stream from his mouth; Fiery sparks escape. (12) Out of his nostrils comes smoke As from a steaming, boiling cauldron. (13) His breath ignites coals; Flames blaze from his mouth. (14) Strength resides in his neck; Power leaps before him. (15) The layers of his flesh stick together; He is as though cast hard; he does not totter. (16) His heart is cast hard as a stone, Hard as the nether millstone. (17) Divine beings are in dread as he rears up; As he crashes down, they cringe. (18) No sword that overtakes him can prevail, Nor spear, nor missile, nor lance. (19) He regards iron as straw, Bronze, as rotted wood. (20) No arrow can put him to flight; Slingstones turn into stubble for him. (21) Clubs are regarded as stubble; He scoffs at the quivering javelin. (22) His underpart is jagged shards; It spreads a threshing-sledge on the mud. (23) He makes the depths seethe like a cauldron; He makes the sea [boil] like an ointment-pot. (24) His wake is a luminous path; He makes the deep seem white-haired. (25) There is no one on land who can dominate him, Made as he is without fear. (26) He sees all that is haughty; He is king over all proud beasts.

(בראשית א, כא) ויברא אלקים את התנינים הגדולים הכא תרגימו ארזילי דימא ר' יוחנן אמר זה לויתן נחש בריח ולויתן נחש עקלתון שנאמר (ישעיהו כז, א) ביום ההוא יפקוד ה' בחרבו הקשה וגו':

אמר רב יהודה אמר רב כל מה שברא הקב"ה בעולמו זכר ונקבה בראם אף לויתן נחש בריח ולויתן נחש עקלתון זכר ונקבה בראם ואלמלי נזקקין זה לזה מחריבין כל העולם כולו מה עשה הקב"ה סירס את הזכר והרג הנקבה ומלחה לצדיקים לעתיד לבא שנאמר (ישעיהו כז, א) והרג את התנין אשר בים

התם נמי ליסרסיה לזכר וליצננה לנקבה דגים פריצי וליעביד איפכא איבעית אימא נקבה מליחא מעלי איבעית אימא כיון דכתיב (תהלים קד, כו) לויתן זה יצרת לשחק בו בהדי נקבה לאו אורח ארעא הכא נמי לימלחה לנקבה כוורא מליחא מעלי בשרא מליחא לא מעלי

כי אתא רב דימי א"ר יונתן עתיד גבריאל לעשות קניגיא עם לויתן שנאמר (איוב מ, כה) התמשוך לויתן בחכה ובחבל תשקיע לשונו ואלמלא הקב"ה עוזרו אין יכול לו שנאמר (איוב מ, יט) העושו יגש חרבו

כי אתא רב דימי אמר רבי יוחנן בשעה שלויתן רעב מוציא הבל מפיו ומרתיח כל מימות שבמצולה שנאמר (איוב מא, כג) ירתיח כסיר מצולה ואלמלא מכניס ראשו לגן עדן אין כל בריה יכולה לעמוד בריחו שנאמר (איוב מא, כג) ים ישים כמרקחה

ובשעה שצמא עושה תלמים תלמים בים שנאמר (איוב מא, כד) אחריו יאיר נתיב אמר רב אחא בר יעקב אין תהום חוזר לאיתנו עד שבעים שנה שנאמר (איוב מא, כד) יחשוב תהום לשיבה ואין שיבה פחותה משבעים

אמר רבה א"ר יוחנן עתיד הקב"ה לעשות סעודה לצדיקים מבשרו של לויתן שנאמר (איוב מ, ל) יכרו עליו חברים ואין כרה אלא סעודה שנאמר (מלכים ב ו, כג) ויכרה להם כרה גדולה ויאכלו וישתו ואין חברים אלא תלמידי חכמים שנאמר (שיר השירים ח, יג) היושבת בגנים חברים מקשיבים לקולך השמיעני

והשאר מחלקין אותו ועושין בו סחורה בשוקי ירושלים שנאמר (איוב מ, ל) יחצוהו בין כנענים ואין כנענים אלא תגרים שנאמר (הושע יב, ח) כנען בידו מאזני מרמה לעשק אהב ואי בעית אימא מהכא (ישעיהו כג, ח) אשר סוחריה שרים כנעניה נכבדי ארץ

ואמר רבה א"ר יוחנן עתיד הקב"ה לעשות סוכה לצדיקים מעורו של לויתן שנאמר (איוב מ, לא) התמלא בשכות עורו זכה עושין לו סוכה לא זכה עושין לו צלצל שנאמר (איוב מ, לא) ובצלצל דגים ראשו

והשאר פורסו הקב"ה על חומות ירושלים וזיוו מבהיק מסוף העולם ועד סופו שנאמר (ישעיהו ס, ג) והלכו גוים לאורך ומלכים לנוגה זרחך:

Bava Batra 74b

“And God created the great sea monsters” (Genesis 1:21). Here, in Babylonia, they interpreted this as a reference to the sea oryx. Rabbi Yoḥanan says: This is leviathan the slant serpent, and leviathan the tortuous serpent, as it is stated: “In that day the Lord with His sore and great and strong sword will punish leviathan the slant serpent, and leviathan the tortuous serpent” (Isaiah 27:1).

Rav Yehuda says that Rav says: Everything that the Holy One, Blessed be He, created in His world, He created male and female. Even leviathan the slant serpent and leviathan the tortuous serpent He created male and female. And if they would have coupled and produced offspring, they would have destroyed the entire world. What did the Holy One, Blessed be He, do? He castrated the male and killed the female, and salted the female to preserve it for the banquet for the righteous in the future. As it is stated: “And He will slay the serpent that is in the sea” (Isaiah 27:1)

There too, with regard to the leviathan, let Him castrate the male and cool the female; why was it necessary to kill the female? The Gemara answers: Fish are unrestrained, and therefore even if the female was cooled, the female would still procreate. The Gemara suggests: And let Him do the opposite, and kill and preserve the male leviathan. The Gemara responds: If you wish, say that the salted female is better; if you wish, sayinstead that since it is written: “There is leviathan, whom You have formed to sport with” (Psalms 104:26), the male must be left alive for sport, because it is not proper conduct to sport with a female. The Gemara asks: Here too,with regard to the beasts, let Him preserve the female in salt, instead of cooling it. The Gemara answers: Salted fish is good, but salted meat is not good.

When Rav Dimi came from Eretz Yisrael to Babylonia he said that Rabbi Yonatan says: In the future, Gabriel will perform a hunt of the leviathan, as it is stated: “Can you draw out leviathan with a fish hook? Or press down his tongue with a cord?” (Job 40:25). And were the Holy One, Blessed be He, not assisting Gabriel, he would not be able tohunt it, as it is stated: “Only He Who made him can use His sword to approach him” (Job 40:19).

When Rav Dimi came from Eretz Yisrael to Babylonia, he said that Rabbi Yoḥanan said: When the leviathan is hungry, he produces breath from his mouth and thereby boils all of the waters in the depths of the sea. As it is stated: “He makes the deep boil like a pot” (Job 41:23). And if the leviathan did not place its head in the Garden of Eden, no creature could withstand his foul smell, as it is stated: “He makes the sea like a seething mixture [merkaḥa]” (Job 41:23), and the term merkaḥa is also used to describe something with a smell (see Exodus 30:25).

And when he is thirsty, he makes many furrows in the sea, as it is stated: “He makes a path to shine after him” (Job 41:24). Rav Aḥa bar Yaakov says:After the leviathan drinks from the sea, the depth of the sea does not return to its normal condition until seventy years have passed, as it is stated: “One would think the deep to be hoary” (Job 41:24), and hoary indicates a person who is no less than seventy years old.

Rabba says that Rabbi Yoḥanan says: In the future, the Holy One, Blessed be He, will make a feast for the righteous from the flesh of the leviathan, as it is stated: “The ḥabbarim will make a feast [yikhru] of him” (Job 40:30). And kera means nothing other than a feast, as it is stated: “And he prepared [va’yikhreh] for them a great feast [kera]; and they ate and drank” (II Kings 6:23). And ḥabbarim means nothing other than Torah scholars, as it is stated: “You that dwell in the gardens, the companions [ḥaverim]

And with regard to the remainder of the leviathan, they will divide it and use it for commerce in the markets of Jerusalem, as it is stated: “They will part him among the kena’anim” (Job 40:30). And kena’anim means nothing other than merchants, as it is stated: “As for the merchant [kena’an], the balances of deceit are in his hand. He loves to oppress” (Hosea 12:8). And if you wish, say that the proof is from here: “Whose merchants are princes, whose traffickers [kinaneha] are the honorable of the earth” (Isaiah 23:8).

And Rabba says that Rabbi Yoḥanan says: In the future, the Holy One, Blessed be He, will prepare a sukka for the righteous from the skin of the leviathan, as it is stated: “Can you fill his skin with barbed irons [besukkot]” (Job 40:31). If one is deserving of being called righteous, an entire sukka is prepared for him from the skin of the leviathan; if one is not deserving of this honor, a covering is prepared for his head, as it is stated: “Or his head with fish-spears” (Job 40:31).

And with regard to the remaining part of the skin of the leviathan, the Holy One, Blessed be He, spreads it on the walls of Jerusalem, and its glory radiates from one end of the world until the other end. As it is stated: “And nations shall walk in your light, and kings at the brightness of your rising”(Isaiah 60:3).

The fish said to Jonah, Don't you know that my day has arrived to be devoured by the Leviathan's mouth? Jonah replied, Take me beside it, and I will deliver you and myself from its mouth. It brought him next to the Leviathan. (Jonah) said to the Leviathan, On your account have I descended to see your home in the sea, for in the future will I descend and put a rope in your tongue, and I will bring you up and prepare you for the great feast of the righteous. (Jonah) showed the Leviathan the seal of our father Abraham (saying), Look at the Covenant, and Leviathan saw it and fled before Jonah a distance of two days' journey.
