Hebrews 7:18-28
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.
7:20 And since this was not done without a sworn affirmation – for the others have become priests without a sworn affirmation,
7:21 but Jesus did so with a sworn affirmation by the one who said to him, “The Lord has sworn and will not change his mind, ‘You are a priest forever’” –
7:22 accordingly Jesus has become the guarantee of a better covenant.
7:23 And the others who became priests were numerous, because death prevented them from continuing in office,
7:24 but he holds his priesthood permanently since he lives forever.
7:25 So he is able to save completely those who come to God through him, because he always lives to intercede for them.
7:26 For it is indeed fitting for us to have such a high priest: holy, innocent, undefiled, separate from sinners, and exalted above the heavens.
7:27 He has no need to do every day what those priests do, to offer sacrifices first for their own sins and then for the sins of the people, since he did this in offering himself once for all.
7:28 For the law appoints as high priests men subject to weakness, but the word of solemn affirmation that came after the law appoints a son made perfect forever.
