Wilt thou break a leaf driven to and fro? - Job here means to say that the treatment of God in regard to him was like treading down a leaf that was driven about by the wind - an insigni ficant, unsettled, and worthless thing. “Wouldst thou show thy power against such an object?” - The sense is, that it was not worthy of God thus to pursue one so unimportant, and so incapable of offering any resistance.
And wilt thou pursue the dry stubble? - Is it worthy of God thus to contend with the driven straw and stubble of the field? To such a leaf, and to such stubble, he compares himself; and he asks whether God could be employed in a work such as that would be, of pursuing such a flying leaf or driven stubble with a desire to overtake it, and wreak his vengeance on it.
