Job ch 41  Leviathan Is a dinosaur, a huge lizard living in a swamp.
The whole plain context of the chapter says this.
  But, despite this obvious fact, every commentary I can find; for
example (https://enduringword.com/bible-commentary/job-41/),
 loudly says that  Leviathan is Satan, and that the whole chapter is
an allegory.   They say the whole chapter is about Job wrestling with
Satan. And, to be fair, you can make an allegory saying this. But it
cannot be the main context of the passage.
 The main problem once again is people bringing in verses from
elsewhere, inductive reasoning, and changing the context of the whole
chapter.
