However, I have followed the general opinion by treating him as the crocodile throughout these notes; but could not finish without stating my doubts on the subject, though I have nothing better to offer in the place of the animal in behalf of which almost all learned men and critics argue, and concerning which they generally agree. As to its being an emblem either of Pharaoh or the devil, I can say little more than, I doubt. The description is extremely dignified; and were we sure of the animal, I have no doubt we should find it in every instance correct. But after all that has been said, we have yet to learn what leviathan is!

Matthew Henry Commentary

--The description of the Leviathan, is yet further to convince Job of his own weakness, and of God's almighty power. Whether this Leviatha be a whale or a crocodile, is disputed. The Lord, having showed Job ho unable he was to deal with the Leviathan, sets forth his own power in that mighty creature. If such language describes the terrible force of Leviathan, what words can express the power of God's wrath? Under humbling sense of our own vileness, let us revere the Divine Majesty take and fill our allotted place, cease from our own wisdom, and giv all glory to our gracious God and Saviour. Remembering from whom ever good gift cometh, and for what end it was given, let us walk humbl with the Lord __________________________________________________________________
