Bible Verses About The High Priest: Being of the order of Aaron

Now if there were perfection through the Levitical priesthood (for under it the people have received the law), what further need was there for another priest to arise after the order of Melchizedek, and not be called after the order of Aaron?

For the priesthood being changed, there is of necessity a change made also in the law.

For he of whom these things are said belongs to another tribe, from which no one has officiated at the altar.

For it is evident that our Lord has sprung out of Judah, about which tribe Moses spoke nothing concerning priesthood.

This is yet more abundantly evident, if after the likeness of Melchizedek there arises another priest,

who has been made, not after the law of a fleshly commandment, but after the power of an endless life:

for it is testified, “You are a priest forever, according to the order of Melchizedek.”
