Blood has been an issue since the fall of man in the garden.
The first blood shed was when God had to kill animals to
make coverings for Adam and Eve. He wrapped them in bloody fur and as they
looked at the blood covering their own skin, they were reminded of the
consequence of what they did. They became conscious of sin.
Without shedding of blood there is no remission of sin
(Hebrews 9:22).
When God instituted the priesthood, He gave instructions for
the way Israel was to offer sacrifices for their sin.
