It does not specifically mention Jesus..
No, but it has things there that apply to what Jesus did and the redeemer is mentioned.
A new covenant is such an important thing, to be left so vague.
It relies too much on the infallibility of men.
Prophets of old did not leave such room for doubt.
eg. the ten commandments
The New Covenant of grace and of the Spirit is more vague I guess in the prophecies of it. But then again I think any prophecies of the Covenant of Moses were pretty vague. When the Covenant came it was no doubt more concrete. Actually I don't think that what Moses would do is called a Covenant in prophecy before it came.
Forgiveness is taught about the New Covenant. Putting His Spirit in us and changing us so that we want to obey the law and are able to.
Knowing God is part of it.
Salvation is promised for Israel and for the Gentiles through the Messiah and that is the forgiveness and redemption and newness of life in the New Covenant.
Jer 31:31 “The days are coming,” declares the Lord,
“when I will make a new covenant
with the people of Israel
and with the people of Judah.
32 It will not be like the covenant
I made with their ancestors
when I took them by the hand
to lead them out of Egypt,
because they broke my covenant,
though I was a husband to them,”
declares the Lord.
33
“This is the covenant I will make with the people of Israel
after that time,” declares the Lord.
“I will put my law in their minds
and write it on their hearts.
I will be their God,
and they will be my people.
34 No longer will they teach their neighbor,
or say to one another, ‘Know the Lord,’
because
they will all know me,
from the least of them to the greatest,”
declares the Lord.
“
For I will forgive their wickedness
and will remember their sins no more.”
Ezek 36:24 “‘For I will take you out of the nations; I will gather you from all the countries and bring you back into your own land. 25 I will sprinkle clean water on you, and you will be clean;
I will cleanse you from all your impurities and from all your idols. 26 I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh. 27 And I will put my Spirit in you and move you to follow my decrees and be careful to keep my laws. 28 Then you will live in the land I gave your ancestors; you will be my people, and I will be your God. 29 I will save you from all your uncleanness.
Jer 23:5 “The days are coming,” declares the Lord,
“when
I will raise up for David a righteous Branch,
a King who will reign wisely
and do what is just and right in the land.

In his days Judah will be saved
and Israel will live in safety.
This is the name by which he will be called:
The Lord Our Righteous Savior.
Isa 59:20 “
The Redeemer will come to Zion,
to those in Jacob who repent of their sins,”
declares the Lord.
21 “As for me,
this is my covenant with them,” says the Lord.
“My Spirit, who is on you, will not depart from you, and my words that I have put in your mouth will always be on your lips, on the lips of your children and on the lips of their descendants—from this time on and forever,” says the Lord.
Isa 49:6 he says:
“It is too small a thing for you to be my servant
to restore the tribes of Jacob
and bring back those of Israel I have kept.
I will also make you a
light for the Gentiles,
that
my salvation may reach to the ends of the earth.”
