The original text was NOT in a chapter and verse format.
There was no Isaiah 53, or 52 or whatever.
In fact there weren't even spaces between words.
And it was written right to left.
A good place to break the verses into paragraphs would have been at Isaiah 52:
Verse 1 to 6 refers to Israel:
.
.
.
.
5 “And now what do I have here?” declares the Lord.
“For my people have been taken away for nothing,
and those who rule them mock,”
declares the Lord.
“And all day long
my name is constantly blasphemed.
6 Therefore my people will know my name;
therefore in that day they will know
that it is I who foretold it.
Yes, it is I.”
Verse 7 is about the Ministry
7 How beautiful on the mountains
are the feet of those who bring good news,
who proclaim peace,
who bring good tidings,
who proclaim salvation,
who say to Zion,
“Your God reigns!”
Vers 8 to 13 is Israel
Listen! Your watchmen lift up their voices;
together they shout for joy.
When the Lord returns to Zion,
they will see it with their own eyes.
9 Burst into songs of joy together,
you ruins of Jerusalem,
for the Lord has comforted his people,
he has redeemed Jerusalem.
.

Verse 9 through the rest of Isaiah 52 and all of 53 is a single figure who is rejected, killed and rises again.
See, my servant will act wisely;
he will be raised and lifted up and highly exalted.
14 Just as there were many who were appalled at him—
his appearance was so disfigured beyond that of any human being
and his form marred beyond human likeness—
15 so he will sprinkle many nations,
and kings will shut their mouths because of him.
For what they were not told, they will see,
and what they have not heard, they will understand.
.
.
.
After he has suffered,
he will see the light of life and be satisfied;
by his knowledge my righteous servant will justify many,
and he will bear their iniquities.
12 Therefore I will give him a portion among the great,
and he will divide the spoils with the strong,
because he poured out his life unto death,
and was numbered with the transgressors.
For he bore the sin of many,
and made intercession for the transgressors.
THIS IS A THEME OF THE TANAKH - THE SUFFERING LAMB OF GOD WHO REDEEMS (PAYS THE PRICE) FOR OUR SIN. A REIGNING KING CANNOT DO THIS. ZECHARIAH STITCHES TOGETHER THE SUFFERING SAVIOR AND THE REIGNING MESSIASH AS ONE PERSON.
