Leviticus 11:10-12

New Revised Standard Version Catholic Edition

¹⁰ But anything in the seas or the streams that does not have fins and scales, of the swarming creatures in the waters and among all the other living creatures that are in the waters—they are detestable to you ¹¹ and detestable they shall remain. Of their flesh you shall not eat, and their carcasses you shall regard as detestable. ¹² Everything in the waters that does not have fins and scales is detestable to you.
