For they indeed became priests without an oath, but He became Priest with an oath by Him who said to Him, “יהוה has sworn and shall not regret, ‘You are a priest forever according to the order of Malkitseḏeq.’ ”
without father, without mother, without genealogy, having neither beginning of days nor end of life, but having been made like the Son of Elohim, remains a priest for all time.
Truly, then, if perfection were through the Lĕwitical priesthood – for under it the people were given the Torah – why was there still need for another priest to arise according to the order of Malkitseḏeq, and not be called according to the order of Aharon?
