Hebrews 7:15
All this becomes even yet plainer when we remember that a new priest has appeared, resembling Melchizedek,
Hebrews 7:3
There is no record of his father, or mother, or lineage, nor again of any beginning of his days, or end of his life. In this he resembles the Son of God, and stands before us as a priest whose priesthood is continuous.
Hebrews 7:11
If, then, Perfection had been attainable through the Levitical priesthood--and it was under this priesthood that the people received the Law--why was it still necessary that a priest of a different order should appear, a priest of the order of Melchizedek and not of the order of Aaron?
Hebrews 7:17-21
for that is the meaning of the declaration-- 'Thou art for all time a priest of the order of Melchizedek.'
