Hebrews 7:20-25

And none of this happened without an oath. For others became priests without an oath,

but Jesus became 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.’”

Because of this oath, Jesus has become the guarantee of a better covenant.

Now there have been many other priests, since death prevented them from continuing in office.

But because Jesus lives forever, He has a permanent priesthood.

Therefore He is able to save completely those who draw near to God through Him, since He always lives to intercede for them.
