Hebrews 7:22-24

Amplified Bible

²² And so [because of the oath’s greater strength and force] Jesus has become the certain guarantee of a better covenant [a more excellent and more advantageous agreement; one that will never be replaced or annulled].

²³ The [former successive line of] priests, on the one hand, existed in greater numbers because they were each prevented by death from continuing [perpetually in office]; ²⁴ but, on the other hand, Jesus holds His priesthood permanently and without change, because He lives on forever.
