Hebrews 7:21-25

21but 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’” –

22accordingly Jesus has become the guarantee of a better covenant.

23And the others who became priests were numerous, because death prevented them from continuing in office,

24but he holds his priesthood permanently since he lives forever.

25So he is able to save completely those who come to God through him, because he always lives to intercede for them.
