Rabbi Moshe Eiseman (Art Scroll Tanach Series, Yechezkiel) explains that in the future the Land (from far in the north) will be divided into 13 sections, from North to South:

Dan

Asher

Naphtali

Manasseh

Ephraim

Reuben

Yehudah

MIDDLE SECTION

Benjamin

Simeon

Issachar

Zebulon

Gad

The MIDDLE SECTION will be divided into five parts. A strip along the east
and a strip along the west will go to the ruler, i.e. The two outer parts
will belong to the Messianic Prince (Nasi= Prince, in Hebrew) who will
rule all Israel. Between the two outer strips on the east and west the
remainder will be divided (from north to south) into three: The middle part
(of the MIDDLE SECTION) will be divided into three:

a. The Temple Mount area which includes the Temple area and housing for the
priests (Cohens);

b. The Levite area

c. The city plus communal land for all the tribes together.

All these divisions are referring only to a division along the coast from
Egypt to Turkey which is divided equally between all the tribes. Another
division takes place to the east based on other criteria.
The present chapter discusses the Middle Section.
We are explaining it mainly in the light of the Commentaries of Rabbi
Eiseman and Y.Z. Moshkovitz (Daat Mikra, Sefer Yechezkiel, Hebrew).

  <<THE SUBURBS>>: In Hebrew migrashdenoting open space.

Describing the place of the Temple. The Temple consisted of two courtyards
beside each other. They were surrounded by a wall. There was an outer
courtyard and an inner courtyard slightly higher than the outer one and
divided from it by steps and a wall. In the inner courtyard there was a two
story altar outside in the open. A ramp from the ground reached to the top
of the altar. After the altar there was a building (The Sanctuary) which
was divided inside into two by a curtain.  Behind the curtain was the Holy
of Holies (THE MOST HOLY PLACE) which was the most sacred area of the Temple.

The priests have to maintain a higher level of ritual purity than other
Israelites so it is better that they dwell together close to the Temple area.

<<TWENTY CHAMBERS>>: The Malbim says this means the equivalent of twenty cities.

The leaders of Israel will no longer oppress them. They will no longer take unfair taxes and not be unjust.

<<YOUR EXACTIONS>>: in Hebrew Gerushotaychemfrom the root Gerushto
divorce, drive away. Unfair government drives a person out of his
inheritance. This is a principle of Biblical Law that every person should
have an inherited right to maintain himself and his family. In an
agricultural society this meant a portion of land that was substantially
inalienable. It would always by right belong to the person who inherited it
and every Israelite was born with the right to such an inheritance. Unjust
social policies and oppressive government were the cause of this right
being unfairly taken away from a person.

These were measurements. The measurements had to be fair. They needed to be
checked. Some of the measurements used in Biblical times by the Israelites
are the same as traditional Anglo-Saxon ones.

The Prince receives the offerings and offers them up for the people who eat and drink portions of them at Festival time.

We dedicate ourselves to God and (even though we and our families benefit
from this, and enjoy it)  it is still considered a sacrifice by means of
which God brings us back to Himself.

<<THAT IS SIMPLE>>: In Hebrew Shogeh= in error, mistaken. It is quite
likely that with so many people involved somebody is liable to make a
mistake and accidentally defile areas of the Temple so these will be annually purified.

You shall keep the Passover and eat meat and matzot (UNLEAVENED BREAD)
which can be quite tasty but initially need a certain culinary dedication.
