'Unclean to You' in the Bible

And the swine, though it divides the hoof, and is cloven footed, yet it chews not the cud; it is unclean to you.

Of their flesh shall you not eat, and their carcass shall you not touch; they are unclean to you.

These are unclean to you among all that creep: whosoever does touch them, when they are dead, shall be unclean until the evening.
