Job 41:30
Sharp stones are under him: he spreadeth sharp pointed things upon the mire.
Sharp stones are under him,.... And yet give him no pain nor uneasiness;
he spreadeth sharp pointed things upon the mire; and makes his bed of them and lies upon them; as sharp stones, as before, shells of fishes, broken pieces of darts, arrows, and javelins thrown at him, which fall around him: this does not so well agree with the crocodile, the skin of whose belly is soft and thin; wherefore dolphins plunge under it and cut it with a thorn, as Pliny {h} relates, or with spiny fins {i}; but with the whale, which lies among hard rocks and sharp stones, and large cutting pieces of ice, as in the northern seas.
