Deuteronomy 14:7

Nevertheless these ye shall not eat of them that chew the cud, or of them that divide the cloven hoof; as the camel, and the hare, and the coney: for they chew the cud, but divide not the hoof; therefore they are unclean unto you.

Cross-reference

Leviticus 7:21 addresses uncleanness from touching any unclean animal—directly applies the same dietary classification.

Leviticus 11:6 gives the identical law about the hare chewing cud but no split hoof—parallel passage.
