Notes

The enormous size of the Leviathan is described by Johanan bar Nappaha, from whom proceeded nearly all the aggadot concerning this monster: "Once we went in a ship and saw a fish which put his head out of the water. He had horns upon which was written: 'I am one of the meanest creatures that inhabit the sea. I am three hundred miles in length, and enter this day into the jaws of the Leviathan'" (B. B. l.c.).

When the Leviathan is hungry, reports Rabbi Dimi in the name of Rabbi Johanan, he sends forth from his mouth a heat so great as to make all the waters of the deep boil, and if he would put his head into Paradise no living creature could endure the odor of him (ib.). His abode is the Mediterranean Sea; and the waters of the Jordan fall into his mouth (Bek. 55b; B. B. l.c.).

In a legend recorded in the Midrash called Pirke de-Rabbi Eliezer it is stated that the fish which swallowed Jonah narrowly avoided being eaten by the Leviathan, which eats one whale each day.

The body of the Leviathan, especially his eyes, possesses great illuminating power. This was the opinion of Rabbi Eliezer, who, in the course of a voyage in company with Rabbi Joshua, explained to the latter, when frightened by the sudden appearance of a brilliant light, that it probably proceeded from the eyes of the Leviathan. He referred his companion to the words of Job xli. 18: "By his neesings a light doth shine, and his eyes are like the eyelids of the morning" (B. B. l.c.). However, in spite of his supernatural strength, the leviathan is afraid of a small worm called "kilbit", which clings to the gills of large fish and kills them (Shab. 77b).[6]

In the eleventh century piyyut (religious poem), Akdamut, recited on Shavuot (Pentecost), it is envisioned that, ultimately, God will slaughter the Leviathan, which is described as having "mighty fins" (and, therefore, a kosher fish, not an inedible snake or crocodile), and it will be served as a sumptuous banquet for all the righteous in Heaven.
