"If
an ox shall gore a man or a woman and he shall die, the ox shall surely
be stoned; its flesh may not be eaten and the owner of the ox shall be
innocent."
Since “... the ox shall surely be stoned...”
means that it died without proper slaughtering and is forbidden for
consumption, then “...its flesh may not be eaten...” teaches that even
if the owner slaughtered it, its meat is still forbidden.
And
“...the owner of the ox shall be innocent (clean)...” teaches that he
can't sell it, as people say, “so-and-so has gone out clean of his
possessions.”
