the key to understanding the scriptures is not in scholarship, ancient languages, polysyllabic concepts, or deep unfathomable meanings. it is right before our very eyes, so simple and so obvious that a small child can easily put their finger on it.
there is a father and there is a son. the father has passed on to his son all of the good things he posesses. the son is a junior, so you have like david sr and david junior. sometimes they get mixed up. it is really that simple. all the rest are the devils workshop - contention for contention's sake.
