Deuteronomy 14:8-10

⁸The pig, because it has a split hoof but doesn’t chew the cud, is unclean to you. You shall not eat their meat. You shall not touch their carcasses.

⁹These you may eat of all that are in the waters: you may eat whatever has fins and scales.

¹⁰You shall not eat whatever doesn’t have fins and scales. It is unclean to you.
