Leviticus 11:9-12

“ ‘Of the animals that live in the sea or in a river, if the animal has fins and scales, you may eat it. But whatever lives in the sea or in a river and does not have fins and scales—including the things that fill the water and all other things that live in it—you should hate. You must not eat any meat from them or even touch their dead bodies, because you should hate them. You must hate any animal in the water that does not have fins and scales.
