Hebrews 7:11

Now if perfection [a perfect fellowship between God and the worshiper] had been attained through the Levitical priesthood (for under it the people were given the Law) what further need was there for another and different kind of priest to arise, one in the manner of Melchizedek, rather than one appointed to the order of Aaron?

And this becomes even more evident if another priest arises in the likeness of Melchizedek,

Hebrews 7:21

(for those Levites who formerly became priests [received their office] without [its being confirmed by the taking of] an oath, but this One [was designated] with an oath through the One who said to Him,

The Lord has sworn
And will not change His mind or regret it,
You (Christ) are a Priest forever’”).

Hebrews 8:10-13


For this is the covenant that I will make with the house of Israel
After those days, says the Lord:
I will imprint My laws upon their minds [even upon their innermost thoughts and understanding],
And engrave them upon their hearts [effecting their regeneration].
And I will be their God,
And they shall be My people.

Hebrews 10:1-4

For since the Law has only a shadow [just a pale representation] of the good things to come—not the very image of those things—it can never, by offering the same sacrifices continually year after year, make perfect those who approach [its altars].

Summary

If therefore perfection were by the Levitical priesthood, (for under it the people received the law,) what further need was there that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron?
