Leviticus 11:8-10

Revised Standard Version Catholic Edition

⁸ Of their flesh you shall not eat, and their carcasses you shall not touch; they are unclean to 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 rivers, you may eat. ¹⁰ But anything in the seas or the rivers that has not fins and scales, of the swarming creatures in the waters and of the living creatures that are in the waters, is an abomination to you.
