Hebrews 7:16-19

7:16 who has become a priest not by a legal regulation about physical descent but by the power of an indestructible life. 7:17 For here is the testimony about him:You are a priest forever in the order of Melchizedek.” 7:18 On the one hand a former command is set aside because it is weak and useless, 7:19 for the law made nothing perfect. On the other hand a better hope is introduced, through which we draw near to God.
