as also in another place God ¹  says, “You are a priest forever in the order of Melchizedek.” ² 

and he was designated ¹  by God as high priest in the order of Melchizedek. ² 

For he was still in his ancestor Abraham’s loins ¹  when Melchizedek met him.

And this is even clearer if another priest arises in the likeness of Melchizedek,

For here is the testimony about him: ¹  “You are a priest forever in the order of Melchizedek.” ² 

where Jesus our forerunner entered on our behalf, since he became a priest forever in the order of Melchizedek. ¹ 

Now this Melchizedek, king of Salem, priest of the most high God, met Abraham as he was returning from defeating the kings and blessed him. ¹ 

So if perfection had in fact been possible through the Levitical priesthood – for on that basis ¹  the people received the law – what further need would there have been for another priest to arise, said to be in the order of Melchizedek and not in Aaron’s order?
