Jesus, our Compassionate Conquering King,
You, Yahweh, are God and cannot lie.
In our oaths, we must swear by that which is greater than us;
there is none greater than You.
So when You take an oath, You swear by Yourself.
Your Father, the Lord, swore an oath
that bound the Unchanging God, who does not change His mind:
You, King Jesus, are a priest forever.
In ages past, You established the priests through Aaron’s line
to prepare the way for You to fulfill and finish priesthood.
Aaron’s priesthood was established without an oath
because it would not last forever.
Aaron and his line were priests in the Old Covenant, whose time has come and gone.
Since You have come as a new Priest,
You have become the guarantee of a better covenant, the promised New Covenant.
You are far outnumbered by Aaron and his descendants;
they outnumber you because they were prevented by death from remaining in office.
But death died in You and has no claim;
You remain forever, and hold Your priesthood permanently.
You are the forever King, and You are the forever Priest.
You always live to intercede for us,
so our confidence in You stands upon bedrock.
Since we have a forever Priest, we have no fear of weakness in Your salvation,
for You are always able to save to the uttermost those of us who come to God through You.
Everything we could ask for, hope for, and need in a priest
we have in You:
holy, innocent, undefiled, separated from sinners, and exalted above the heavens.
As such, You had no need to offer sacrifices for Yourself,
but You offered sacrifice for our sins–You offered Yourself—
once for all.
All the Old Covenant could do was appoint weak men captive to sin and death.
You did this, in Your great wisdom, so that we could look for and long for something better.
Better than better, Your Father appointed His Son,
who has been perfected forever.
This is the kind of high priest we need,
and in You, Jesus, this is the high priest we have.
You are reigning at the right hand of the Majesty in the heavens,
ministering in the sanctuary which You, the Lord, set up.
You made us to worship, You saved us to worship, You welcome us to worship.
You alone are worthy.
None of this happened [the nullification of the Levitical priesthood by the arrival of Jesus, the Melchizedekean priest] without an oath. For others became priests without an oath, but He with an oath made by the One who said to Him:
The Lord has sworn,
and He will not change His mind,
You are a priest forever.
So Jesus has become the guarantee of a better covenant.
Now many have become Levitical priests, since they are prevented by death from remaining in office. But because He remains forever, He holds His priesthood permanently. Therefore He is always able to save [or, able to save completely] those who come to God through Him, since He always lives to intercede for them.
For this is the kind of high priest we need: holy, innocent, undefiled, separated from sinners, and exalted above the heavens. He doesn’t need to offer sacrifices every day, as high priests do–first for their own sins, then for those of the people. He did this once for all when He offered Himself. For the law appoints as high priests men who are weak, but the promise of the oath, which came after the law, appoints a Son, who has been perfected forever.
Now the main point in what is being said is this: we have this kind of high priest, who sat down at the right hand of the throne of the Majesty in the heavens, a minister of the sanctuary and the true tabernacle, which the Lord set up, not man.
