Job 40:15-24 describes Behemoth, and then the sea-monster Leviathan, to demonstrate to Job the futility of questioning God, who alone has created these beings and who alone can capture them [REF].
Leviathan is identified figuratively with both the primeval sea (, ) and in apocalyptic literature - describing the end-time - as that adversary, the Devil, from before creation who will finally be defeated.
