Deuteronomy 14:7-8

7But among the ones that chew the cud or have divided hooves, you are not to eat these: camels, hares, and hyraxes, though they chew the cud, they do not have hooves — they are unclean for you;

8and pigs, though they have hooves, they do not chew the cud — they are unclean for you. Do not eat their meat or touch their carcasses.
