Hebrews 7:19-24

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.
