Deuteronomy 14:8-10

New Revised Standard Version, Anglicised Catholic Edition

⁸ And the pig, because it divides the hoof but does not chew the cud, is unclean for you. You shall not eat their meat, and you shall not touch their carcasses.

⁹ Of all that live in water you may eat these: whatever has fins and scales you may eat. ¹⁰ And whatever does not have fins and scales you shall not eat; it is unclean for you.
