7:11If indeed then perfection were by the Levitical priesthood, for the people had their law given to them in connexion with *it*, what need was there still that a different priest should arise according to the order of Melchisedec, and not be named after the order of Aaron?

7:12For, the priesthood being changed, there takes place of necessity a change of law also.

7:24but he, because of his continuing for ever, has the priesthood unchangeable.
