5 And when the day, and the power, and the punishment, and the judgement come, which the Lord of Spirits hath prepared for those who worship not the righteous law, and for those who deny the righteous judgement, and for those who take His name in vain--that day is prepared, for the elect a covenant, but for sinners an inquisition.
6 And on that day were two monsters parted, a female monster named Leviathan, to dwell in the abysses of the ocean over the fountains of the waters. 7 But the male is named Behemoth, who occupied with his breast a waste wilderness named †Dûidâin†, on the east of the garden where the elect and righteous dwell, where my grandfather was taken up, the seventh from Adam, the first man whom the Lord of Spirits created.8 And I besought the other angel that he should show me the might of those monsters, how they were parted on one day and cast, the one into the abysses of the sea, and the other unto the dry land of the wilderness. 9 And he said to me: 'Thou son of man, herein thou dost seek to know what is hidden.'
10 And the other angel who went with me and showed me what was hidden told me what is first and last in the heaven in the height, and beneath the earth in the depth, and at the ends of the heaven, and on the foundation of the heaven.

10 But these men do not understand the things they slander, and they are being destroyed by the very things that, like irrational animals, they instinctively comprehend. 11 Woe to them! For they have traveled down Cain’s path, and because of greed have abandoned themselves to Balaam’s error; hence, they will certainly perish in Korah’s rebellion. 12 These men are dangerous reefs at your love feasts, feasting without reverence, feeding only themselves. They are waterless clouds, carried along by the winds; autumn trees without fruit—twice dead, uprooted; 13 wild sea waves, spewing out the foam of their shame; wayward stars for whom the utter depths of eternal darkness have been reserved. 14Now Enoch, the seventh in descent beginning with Adam, even prophesied of them, saying, “Look! The Lord is coming with thousands and thousands of his holy ones, 15 to execute judgment on all, and to convict every person of all their thoroughly ungodly deeds that they have committed, and of all the harsh words that ungodly sinners have spoken against him.”
