They will walk after the Lord [in obedience and worship],
Who will roar like a lion;
He will roar [summoning them]
And His sons will come trembling from the west.

This was to fulfill what was spoken by the prophet:

“I will open My mouth in parables;
I will utter things [unknown and unattainable] that have been hidden [from mankind] since the foundation of the world.”

Now these things happened to them as an example and warning [to us]; they were written for our instruction [to admonish and equip us], upon whom the ends of the ages have come.

For

Now Hagar is (represents) Mount Sinai in Arabia and she corresponds to the present Jerusalem, for she is in slavery with her children.

And when He had taken bread and given thanks, He broke it and gave it to them, saying, “This is My body which is given for you; do this in remembrance of Me.”

and all [of them] drank the same spiritual drink, for they were drinking from a spiritual rock which followed them; and the rock was Christ.

The two

Brothers and sisters, I speak in terms of human relations: even though a last will and testament is just a human covenant, yet when it has been signed and made legally binding, no one sets it aside or adds to it [modifying it in some way].

And so [because of the oath’s greater strength and force] Jesus has become the certain guarantee of a better covenant [a more excellent and more advantageous agreement; one that will never be replaced or annulled].

But as it is, Christ has acquired a [priestly] ministry which is more excellent [than the old Levitical priestly ministry], for He is the Mediator (Arbiter) of a better covenant [uniting God and man], which has been enacted and rests on better promises.

For this reason He is the Mediator and Negotiator of a new covenant [that is, an entirely new agreement uniting God and man], so that those who have been called [by God] may receive [the fulfillment of] the promised eternal inheritance, since a death has taken place [as the payment] which redeems them from the sins committed under the obsolete first covenant.

And the Holy Spirit also adds His testimony to us [in confirmation of this]; for after having said,

and to Jesus, the Mediator of a new covenant [uniting God and man], and to the sprinkled blood, which speaks [of mercy], a better and nobler and more gracious message than the blood of Abel [which cried out for vengeance].

Now may the God of peace [the source of serenity and spiritual well-being] who brought up from the dead our Lord Jesus, the great Shepherd of the sheep, through the blood that sealed and ratified the eternal covenant,

Which

It was for this freedom that Christ set us free [completely liberating us]; therefore keep standing firm and do not be subject again to a yoke of slavery [which you once removed].

For you have not received a spirit of slavery leading again to fear [of God’s judgment], but you have received the Spirit of adoption as sons [the Spirit producing sonship] by which we [joyfully] cry, “Abba! Father!”
