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, the rear of whose padded foot is an undivided, yielding ball, and the hare, and the coney, Leviticus 11:5: for they chew the cud, make the movements characteristic of ruminating, but divide not the hoof; therefore they are unclean unto you.
