Matthew Poole and continuators on Job 41:30

30. Sharp stones are under him: he spreadeth sharp-pointed things upon the mire .

According to this Translation the sense is, His Skin is so hard and impenerable that the sharpest stones are as easie to him as the mire, and make no more impression upon him. But the words are and may be otherwise rendred as continuing the former sense, They (to wit, the Arrows, Darts or Stones cast at him) are, or fall under him, like (which Particle is oft understood) sharp shreads, or fragments of stones, he spreadeth sharp pointed things (to wit, the pieces of Swords or Darts which were flung at him and broken upon him) upon the mire. The fragments of broken weapons lie as thick at the bottom of the Water in the place of the fight, as little stones do in the mire, or as they do in a Field after some fierce and furious Battle. Or thus, with him (or for him, i. e. For his defence) are sharp stones, he spreadeth himself like an harrow, or threshing instrument (which is filled and fortified with Iron) in the mire or mud in the bottom of the Water: So he doth not describe his resting-place, but rather his Back, which he not unfitly compares to sharp stones or threshing Instruments, because the Darts or Stones cast at him pierce no more into him than they would do into them if they were thrown at them.
