The Lord speaks to Moses and Aaron. Among land animals, those that have split hooves and chew the cud may be eaten. The camel, the rock badger, the hare and the pig are named as examples of unclean animals because they do not meet both conditions. Whoever touches their carcasses becomes unclean.
Of water creatures, those with fins and scales may be eaten; everything else is detestable. Then forbidden birds are listed, among them the eagle, the vulture, the raven, the owl and the bat. Of winged insects that go on all fours, the locusts and grasshoppers that hop may be eaten, and the rest are unclean.
The second part deals with uncleanness by contact: whoever touches the carcass of an unclean animal, or one that died without being slaughtered, is unclean until evening and must wash his clothes. Contaminated clay pots are broken. The creatures that swarm on the ground are unclean. The chapter concludes with the basis: the Lord brought Israel out of Egypt to be their God, and so they must be holy because he is holy.
