They shall be even an abomination to you
 This is repeated again and again, to deter from the eating of such fishes, lest there should be any desire after them: 
 ye shall not eat of their flesh,
 here mention is made of the flesh of fishes, as is by the apostle, ( 1 Corinthians 15:39 ) . Aben Ezra observes, that their wise men say, this is according to the usage of words in those ages: 
 but you shall have their carcasses in abomination;
 not only abstain from eating them and touching them, but to express the utmost aversion to them.
