Who is the Rightful High Priest?

Korah leads a rebellion assuming that his standing means he can assert himself as a priest.  But God reminds all of Israel that he has chosen rightly with Aaron.  Whereas Korah attempted to elevate himself and in so doing put the people at risk, the true high priest puts his own life at risk in order to rescue the people.  How much more is this true of Jesus who has once and for all rescued humanity by laying down his life.
