Hebrews 7:21-25

21but this one was made a priest with an oath by the one who said to him: "The Lord has sworn and will not change his mind, 'You are a priest forever.'"

22This makes Jesus the guarantor of a better covenant.

23The former priests were many in number, because they were prevented by death from continuing in office,

24but he holds his priesthood permanently, because he continues forever.

25Consequently, he is able to save to the uttermost those who draw near to God through him, since he always lives to make intercession for them.
