Hebrews 7:21-25

21but there was an oath regarding Jesus. For God said to him, “The Lord has taken an oath and will not break his vow: ‘You are a priest forever.’”

22Because of this oath, Jesus is the one who guarantees this better covenant with God.

23There were many priests under the old system, for death prevented them from remaining in office.

24But because Jesus lives forever, his priesthood lasts forever.

25Therefore he is able, once and forever, to save those who come to God through him. He lives forever to intercede with God on their behalf.
