Fantastic Beasts and Where to Find Them... in the Torah

(20) God said, “Let the waters bring forth swarms of living creatures, and birds that fly above the earth across the expanse of the sky.” (21) God created the great sea monsters, and all the living creatures of every kind that creep, which the waters brought forth in swarms, and all the winged birds of every kind. And God saw that this was good. (22) God blessed them, saying, “Be fertile and increase, fill the waters in the seas, and let the birds increase on the earth.” (23) And there was evening and there was morning, a fifth day.

(10) Till when, O God, will the foe blaspheme, will the enemy forever revile Your name? (11) Why do You hold back Your hand, Your right hand? Draw it out of Your bosom! (12) O God, my King from of old, who brings deliverance throughout the land; (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; (15) it was You who released springs and torrents, who made mighty rivers run dry; (16) the day is Yours, the night also; it was You who set in place the orb of the sun; (17) You fixed all the boundaries of the earth; summer and winter—You made them.

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 slain 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).

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 to hunt it, as it is stated: “Only He Who made him can use His sword to approach him” (Job 40:19).

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] hearken for your voice: Cause me to hear it” (Song of Songs 8:13). This verse is interpreted as referring to Torah scholars, who listen to God’s voice.

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.
