Hebrews 7:11-13

Amplified Bible, Classic Edition

¹¹ Now if perfection (a perfect fellowship between God and the worshiper) had been attainable by the Levitical priesthood—for under it the people were given the Law—why was it further necessary that there should arise another and different kind of Priest, one after the order of Melchizedek, rather than one appointed after the order and rank of Aaron?

¹² For when there is a change in the priesthood, there is of necessity an alteration of the law [concerning the priesthood] as well.

¹³ For the One of Whom these things are said belonged [not to the priestly line but] to another tribe, no member of which has officiated at the altar.
