Hebrews 7:11-14

Living Bible

¹¹ (e) If the Jewish priests and their laws had been able to save us, why then did God need to send Christ as a priest with the rank of Melchizedek, instead of sending someone with the rank of Aaron—the same rank all other priests had?

^12-14 And when God sends a new kind of priest, his law must be changed to permit it. As we all know, Christ did not belong to the priest-tribe of Levi, but came from the tribe of Judah, which had not been chosen for priesthood; Moses had never given them that work.
