New International Version

⁸ The pig is also unclean; although it has a divided hoof, it does not chew the cud. You are not to eat their meat or touch their carcasses.^(A)

⁹ Of all the creatures living in the water, you may eat any that has fins and scales. ¹⁰ But anything that does not have fins and scales you may not eat; for you it is unclean.
