John Wesley on Job 41:34

King, &c. - He can tame both the behemoth and leviathan, as strong and stout - hearted as they are. This discourse concerning them was brought in, to prove that it is God only, who can look upon proud men and abase them, bring them low, and hide them in the dust, he it is that beholdeth all high things, and wherein men dealt proudly, he is above them. He is king over all the children of pride, brutal or rational, and makes them either bend or break before him.
