27:1 leviathan. “Leviathan” is here also called “the dragon.” The references to “leviathan” in Psalm 74:13-14; Psalm 104:26; and Job 41:1-34 make it clear that this was a real animal, probably a fearsome marine reptile, like a dinosaur. This passage, as well as Psalm 74:13,14, also shows that the many references to “dragons” in the Bible (Hebrew tannin) must refer to great monsters, now extinct, such as dinosaurs. Only the false idea of the supposed evolutionary ages of geology says that dinosaurs became extinct seventy million years before man evolved.
27:1 that crooked serpent. Leviathan, though a real animal, also symbolizes that old serpent, the devil, who will indeed be judged “in that day,” first bound in “the bottomless pit,” later consigned forever to “the lake of fire” (Revelation 20:3,10).
27:1 dragon. The “dragon that is in the sea,” actually a marine dinosaur-like reptile (called a plesiosaur today), here symbolizes both Satan and the Beast of the end-times. See Revelation 12:3, 9; 13:1-2. The Beast, the Man of sin, is energized and possessed by Satan. Both will be destroyed “in that day.”
