—In Apocryphal Literature:
Both leviathan and behemoth are prominent in Jewish eschatology. In the Book of Enoch (lx. 7-9), Enoch says
Charles, "Book of Enoch," p. 155; comp. "the secret chambers of leviathan" which Elihu b. Berakel the Buzite will disclose, Cant. R. i. 4).
"On that day [the day of judgment] two monsters will be produced: a female monster, named 'Leviathan,' to dwell in the depths of the ocean over the fountains of the waters; but the male is called 'Behemoth,' who occupies with his breast a waste wilderness named 'Dendain' [read "the land of Naid" after LXX., ?? ?? ?a?d = , Gen. iv. 16], on the east of the garden, where the elect and the righteous dwell. And I besought that other angel that he should show me the might of these monsters; how they were produced on one day, the one being placed in the depth of the sea and the other in the main land of the wilderness. And he spake to me: 'Thou son of man, dost seek here to know what is hidden?'"
According to II Esdras vi. 49-53, God created on the fifth day the two great monsters, leviathan and behemoth, and He separated them because the seventh part of the world which was assigned to the water could not hold them together, and He gave to the behemoth that part which was dried up on the third day and had the thousand mountains which, according to Ps. i. 10, as understood by the haggadists ("the behemoth [A. V. "cattle"] upon a thousand hills"; comp. Lev. R. xxii.; Num. R. xxi.; and Job xl. 20), furnish behemoth with the necessary food. To the leviathan God gave the seventh part of the earth filled with water; and He reserved it for the future to reveal by whom and at what time the leviathan and the behemoth should be eaten.
In the Syriac Apocalypse of Baruch, xxix. 4, also, the time is predicted when the behemoth will come forth from his seclusion on land and the leviathan out of the sea, and the two gigantic monsters, created on the fifth day, will serve as food for the elect who will survive in the days of the Messiah.
