Derek Prince - Leviathan is a Type of Satan
We'll picture the same which you may have never have noticed, in the book of Joel chapter 41. Now the whole of this chapter deals with a creature named Leviathan. There is some kind of marine monster, and we don't know very much about Leviathan, but do you think that the Bible which is so economical would devote 34 verses just to a marine monster? No. The truth is Leviathan is a type or a picture of Satan. You can study this carefully you see this. I only want to point out you the closing statement in Job 41:34, "He beholds every high thing, he's extremely proud, and he is king over all the children of pride".
