Hebrews 7:24-25
KJV—But this (Jesus), because he continueth
ever, hath an unchangeable priesthood.
Wherefore he is able also to save them to
the uttermost that come unto God by him,
seeing he ever liveth to make intercession
for them.

Amp—But He holds His priesthood unchangeably
because He lives on forever.
Therefore He is able also to save to the
uttermost—completely, perfectly, finally
and for all time and eternity—those who
come to God through Him, since He is
always living to make petition to God
and intercede with Him and intervene
for them.

Moffatt—He holds his priesthood without
any successor, since he continues for ever.
Hence for all time he is able to save those
who approach God through him, since he is
always living to intercede on their behalf.

NEB—But the priesthood which Jesus holds
is perpetual, because he remains for ever.
That is why he is also able to save absolutely
those who approach God through him;
he is always living to plead on their behalf.

Hebrews 8:6, 10-12
KJV—But now hath he obtained a more excellent
ministry, by how much also he is the
mediator of a better covenant, which was
established upon better promises.

For this is the covenant that I will make
with the house of Israel after those days, saith
the Lord; I will put my laws into their mind,
and write them in their hearts: and I will be to
them a God, and they shall be to me a people:
And they shall not teach every man his
neighbour, and every man his brother, saying,
Know the Lord: for all shall know me, from
the least to the greatest. For I will be merciful
to their unrighteousness, and their sins and
their iniquities will I remember no more.

Amp—But as it now is, He [Christ] has acquired
a [priestly] ministry which is as much
superior and more excellent [than the old]
as the covenant—the agreement—of which
He is the Mediator (the Arbiter, Agent) is
superior and more excellent; [because] it is
enacted and rests upon more important
(sublimer, higher and nobler) promises.

For this is the covenant that I will make
with the house of Israel after those days,
says the Lord: I will imprint My laws upon
their minds, even upon their innermost
thoughts and understanding, and engrave
them upon their hearts, and I will be their
God, and they shall be My people. And it
will nevermore be necessary for every one
to teach his neighbor and his fellow citizen
or every one his brother, saying, Know—
[that is,] perceive, have knowledge of and
get acquainted by experience with—the
Lord; for all will know Me, from the smallest
to the greatest of them. For I will be merciful
and gracious toward their sins and I will
remember their deeds of unrighteousness
no more.

Moffatt—As it is, however, the divine service
he has obtained is superior, owing to the
fact that he mediates a superior covenant,
enacted with superior promises.

This is the covenant I will make with the
house of Israel when that day comes, saith
the Lord; I will set my laws within their mind,
inscribing them upon their hearts; I will be a
God to them, and they shall be a People
to me; one citizen will no longer teach his
fellow, one man will no longer teach his
brother, saying, ‘Know the Lord,’ for all are
to know me, low and high together. I will be
merciful to their iniquities, and remember
their sins no more.

NEB—But in fact the ministry which has
fallen to Jesus is as far superior to theirs
as are the covenant he mediates and the
promises upon which it is legally secured.

‘For the covenant I will make with the
house of Israel after those days, says the
Lord, is this: I will set my laws in their understanding
and write them on their hearts;
and I will be their God, and they shall be
my people. And they shall not teach one
another, saying to brother and fellow-citizen,
“Know the Lord!” For all of them, high and
low, shall know me; I will be merciful to their
wicked deeds, and I will remember their sins
no more.’
