Hence the fact that the sacrificed animal prophesies both prosperity and misfortune may be taken as an indication of its being a source not only of beneficial influences but of harmful influences as well. As already said, it is a general characteristic of holiness that it is a seat of good and evil at the same time. The rules relating to the eating of the sacrificed animal illustrate this idea, and so do various other facts connected with the Great Feast and its sacrifice.
