The Leviathan is a sea creature. It brings chaos, death and disaster where ever it goes. The Leviathan smells of rotting carcasses. His breath can boil the waters around him and when he sneezes, smoke comes out of its nose. The Hebrews believe that God (Yahweh) made the Leviathan and a female on the fifth day of Creation, but killed her to stop the world being destabilised.
