for the ones trulywithout oath-taking are become priests, but He with oathtaking, through the One saying to Him, The Lord swore, and will not care to change, “You are a priest unto the age according to the order of Melchizedek”; Psalm 110:4
without father, without mother, without descent, nor beginning of days, nor having end of life, but having been made like the Son of God, he remains a priest in perpetual continuity).
