Hebrews 7:11-14

111So if perfection was through the Levitical priesthood (for on the basis of it 2the people received the Law), what further need was there for another priest to arise 3according to the order of Melchizedek, and not be designated according to the order of Aaron?

12For when the priesthood is changed, of necessity there takes place a change of law also.

13For 4the one about whom 5these things are said belongs to another tribe, from which no one has officiated at the altar.

14For it is evident that our Lord 6was 7descended from Judah, a tribe with reference to which Moses said nothing concerning priests.
