Sharp stones are under him: he spreadeth sharp pointed things upon the mire.
Sharp stones - rather, as margin, potsherds х chaduwdeey (H2303) chaares (H2789)]: i:e., the sharp and pointed scales on the belly, like broken pieces of pottery.
Sharp-pointed things - rather, a threshing instrument х chaaruwts (H2742)], but not on the fruits of the earth, but 'on the mire;' irony. When he lies on the mire he leaves the marks of his scales so imprinted on it that one might fancy a threshing instrument with its sharp teeth had been drawn over it (Isaiah 28:27).
