Canst thou draw out leviathan with an hook? or his tongue with a cord which thou lettest down? (Job 41:1)
Behemoth wasn’t an actual animal, but a mythical beast placed here in the story as a literary device to drive the point home.
This is simply as fallacious as liberal RC scholarship which effectively has Christ referring to a fable by invoking the story of Jonah. In contrast, God is invoking His power, wisdom and majesty in the light of creation, and which makes relegating Behemoth ("which I made with thee") and Leviathan to be mythical beasts absurd, for invoking mythical beasts as evidence of the creators power and wisdom is absurd.
And whether you like it or not, sometimes your articles come across as being the product of an elitist who seeks to make a name for himself (and pimp your "Depths of Pentecost" blog) by engaging in dubious corrections, as in His Hand is Stretched Out Still (though such seem to be in the minority).
Behemoth could have been an Aurochs or its wilder predecessor. And other beasts could be, while in these present times unknown, scary critters generally feared and avoided in that time. No sense to call them mythical, as that would not have been convincing.
