Job 41:30

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

His undersides are like sharp potsherds, Leaving a trail in the mud like a threshing sledge.

His underparts are `like' sharp potsherds: He spreadeth `as it were' a threshing-wain upon the mire.

Under him `are' sharp points of clay, He spreadeth gold on the mire.

His undersides are jagged potsherds, spreading out the mud like a threshing sledge.
