God explained to Job that is he can’t even do anything to a fire-breathing Leviathan, then how is he going to defend himself from God’s judgement.
– Leviathan – Some people believe that God described a Whale or a Crocodile, but none of them can produce fire out of their mouth. At the same time, we all know from the history and from tales that only Dinosaurs/Dragons could blow fires out of their mouths. So, Leviathan was some kind of a sea Dinosaur/Dragon and since most people were afraid of them they called them monsters or sea monsters. Also, Leviathan could possibly be some kind of a Pliosauroid or a Pliosaur which was a large marine kind of a reptile.
