Hebrews 7:16-19

16one who has become a priest not on the basis of a regulation as to his ancestry but on the basis of the power of an indestructible life. 17For it is declared: “You are a priest forever, in the order of Melchizedek.” 18The former regulation is set aside because it was weak and useless 19(for the law made nothing perfect), and a better hope is introduced, by which we draw near to God.
