And the Lord created the great tanins, the lev-ya-than and his yoke-fellow which are prepared for the day of consolation, and every living animal which creepeth, and which the clear waters had swarmed forth after their kind; the kinds which are clean, and the kinds which are not clean; and every fowl which flieth with wings after their kinds, the clean and the unclean. And the Lord beheld that it was good.
Leviathan and His Mate Saved for the Day of Consolation
