Hebrews 7:15
And this is still more abundantly clear when we read that it is as belonging to the order of Melchizedek that a priest of a different kind is to arise,
Hebrews 7:3
with no father or mother, and no record of ancestry: having neither beginning of days nor end of life, but made a type of the Son of God--this man Melchizedek remains a priest for ever.
Hebrews 7:11
Now if the crowning blessing was attainable by means of the Levitical priesthood--for as resting on this foundation the people received the Law, to which they are still subject-- what further need was there for a Priest of a different kind to be raised up belonging to the order of Melchizedek instead of being said to belong to the order of Aaron?
Hebrews 7:17-21
For the words are in evidence, "Thou art a priest for ever, belonging to the order of Melchizedek."
