Hebrews 7:15
And this is yet more abundantly clear if, after the likeness of Melchizedek, there arises another Priest,
Hebrews 7:3
without father or mother, without lineage, having neither beginning of days nor end of life, but resembling the Son of God, he remains a priest in perpetuity.
Hebrews 7:11
Now if there were perfection through the Levitical priesthood, (and it was under it that the people received the Law) why was it still necessary for another kind of priest to arise, after the order of Melchizedek, instead of being reckoned according to the order of Aaron?
Hebrews 7:17-21
For the words are in evidence, Thou art a priest forever after the order of Melchizedek.
