Leviticus 11:8-10

New Revised Standard Version, Anglicised

⁸ Of their flesh you shall not eat, and their carcasses you shall not touch; they are unclean for you.

⁹ These you may eat, of all that are in the waters. Everything in the waters that has fins and scales, whether in the seas or in the streams—such you may eat. 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
