'Attained' in the Bible

Now if perfection could have been attained through the Levitical priesthood for on this basis the people received the Law what further need would there be to speak of appointing another kind of priest according to the order of Melchizedek, not one according to the order of Aaron?

But now he has attained a more excellent ministry, by as much as he is also mediator of a better covenant which has been enacted upon better promises.
