   The reason for pouring out the blood, which is so constantly
   and strictly required by the law, was in opposition to an
   idolatrous custom of the ancient Zabii, who "were accustomed

   imagined this to be the food of their gods, with whom they
   thought they had such communion, by eating their meat, that
   they revealed to them future things."--Maimonides
