As they also slayed many animals in sacrifices to God as was the old way. Read the older part of the Bible. It is all in there list by list of what to sacrifice. The story of Abraham was that God tested his faith then instructed him He/She (for Katina I too believe that way) no longer wanted it that way. No more sacrifices. So my friend it did not go over my head, and to explain further he did create the religion Judaism was in existence long before Abraham this story is not about Christianity. That guy came later on and by the way……he was Jewish.
