The word of YHWH to Isaiah the Prophet:

The people who walked in darkness
have seen a great light;
those who dwelt in a land of deep darkness,
on them has light shone.

You have multiplied the nation;
you have increased its joy;
they rejoice before you
as with joy at the harvest,
as they are glad when they divide the spoil.
For the yoke of his burden,
and the staff for his shoulder,
the rod of his oppressor,
you have broken as on the day of Midian.

For every boot of the tramping warrior in battle tumult
and every garment rolled in blood
will be burned as fuel for the fire.
For to us a child is born,
to us a son is given;
and the government shall be upon his shoulder,
and his name shall be called:
Wonderful Counselor, Mighty God,
Everlasting Father, Prince of Peace.
Of the increase of his government and of peace
there will be no end,
on the throne of David and over his kingdom,
to establish it and to uphold it
with justice and with righteousness
from this time forth and forevermore.

The zeal of the LORD of hosts will do this.

The Lord has sent a word against Jacob,
and it will fall on Israel;
and all the people will know,
Ephraim and the inhabitants of Samaria,
who say in pride and in arrogance of heart:
“The bricks have fallen,
but we will build with dressed stones;
the sycamores have been cut down,
but we will put cedars in their place.”
But the LORD raises the adversaries of Rezin against him,
and stirs up his enemies.
The Syrians on the east and the Philistines on the west
devour Israel with open mouth.
For all this his anger has not turned away,
and his hand is stretched out still.

Isaiah 9:6b-7 in the Aleppo Codex

The people did not turn to him who struck them,
nor inquire of the LORD of hosts.
So the LORD cut off from Israel head and tail,
palm branch and reed in one day—
the elder and honored man is the head,
and the prophet who teaches lies is the tail;
for those who guide this people have been leading them astray,
and those who are guided by them are swallowed up.
Therefore the Lord does not rejoice over their young men,
and has no compassion on their fatherless and widows;
for everyone is godless and an evildoer,
and every mouth speaks folly.
For all this his anger has not turned away,
and his hand is stretched out still.

For wickedness burns like a fire;
it consumes briers and thorns;
it kindles the thickets of the forest,
and they roll upward in a column of smoke.
Through the wrath of the LORD of hosts
the land is scorched,
and the people are like fuel for the fire;
no one spares another.
They slice meat on the right, but are still hungry,
and they devour on the left, but are not satisfied;
each devours the flesh of his own arm,
Manasseh devours Ephraim, and Ephraim devours Manasseh;
together they are against Judah.
For all this his anger has not turned away,
and his hand is stretched out still.

Woe to those who decree iniquitous decrees,
and the writers who keep writing oppression,
to turn aside the needy from justice
and to rob the poor of my people of their right,
that widows may be their spoil,
and that they may make the fatherless their prey!
What will you do on the day of punishment,
in the ruin that will come from afar?
To whom will you flee for help,
and where will you leave your wealth?
Nothing remains but to crouch among the prisoners
or fall among the slain.

For all this his anger has not turned away,
and his hand is stretched out still.

(Isaiah 9.2–10.4 ESV)
