Hebrews 7:21-25

21(for they have become priests without an oath, but He with an oath by Him who said to Him: “The Lord has sworn And will not relent, ‘You are a priest forever According to the order of Melchizedek’ ”),

22by so much more Jesus has become a surety of a better covenant.

23Also there were many priests, because they were prevented by death from continuing.

24But He, because He continues forever, has an unchangeable priesthood.

25Therefore He is also able to save to the uttermost those who come to God through Him, since He always lives to make intercession for them.
