As unleavened bread is pure and free from leaven, so is Yeshua is pure. The matzo is a good representation of our Messiah. Let us examine this bread and how Yeshua is typified by this element:

1.    It is pierced.  Yeshua was pierced (Jn 19:24; Ps 22:16; Zech 12:10; Rev
1:7)

 2.  It is bruised. Yeshua was bruised (Isa 28:28; Isa 42:3; Isa 53:5; Matt
12:18-21)

3.  It is striped.  Yeshua was striped.  it is by His stripes we are healed (Isa 53:5)

4.  it is pure. Yeshua was without sin. (2 Cor 2:21; 1 Pet 2:22; Heb 4:15; Jn 14:30)
       a. Only unleavened bread was used in the Temple because the offerings presented there had to be pure.

5.  Yeshua referred to Himself as the "bread of life" in John 6:48.

6.  Yeshua was born in Bethlehem, which means "house of bread." (Heb: bêyth lechem)

7.  Passover typified the substitutionary death of the Messiah, so Unleavened Bread depicts the burial of the Messiah.


UNLEAVENED BREAD DEPICTS BURIAL OF MESSIAH
 
JUST as Pesach (Passover) depicts the substitutionary death of the Messiah, so is the Unleavened Bread depicts the burial of the Messiah.  Yeshua died a criminal's death in the hands of the Romans but His burial was that of a wealthy man. When a criminal dies he would normally be given a criminal's burial but Yeshua was accorded with honour and respect in His burial.  As the Scripture said, Yeshua was buried in new tomb affordable only for the rich people.  The donor of the tomb was His secret follower by the name of Joseph of Arimathaea, who was a member of the Sanhedrin and an influential member of the society.  His burial declared His innocence and purity. Because Yeshua was without sin (leaven), God did not allow His holy body to be treated with disrespect.  His body never decayed or return to dust.  David, king of Israel prophesied in Psalms concerning the burial of the Messiah Yeshua (Jesus Christ) . "As a pure, sinless sacrifice, the Messiah was not under the curse to return to the dust."

Passover is probably the  best known of the Jewish holidays simply because it ties with our Lord`s Last Supper, which was a Passover Seder.   We believe without a doubt that what Jesus (Yeshua) did on that night was very messianic in nature and a lot of its observances and practices are types and shadows pointing to Jesus.

Passover begins on the twilight of the 14th day of the Jewish month of Nisan. It is the first of the three major festivals with both historical and agricultural significance (the other two are Shavu’ot and Sukkot). Agriculturally, it represents the beginning of the harvest season in Israel, but little attention is paid to this aspect of the holy day. The primary observances of Passover are related to the Exodus from Egypt after 400 years of slavery. This story is told in Exodus 1-15. Many of the Passover observances are instituted in Exodus 12-15.

The name “Passover” refers to the fact that the angel of death “passed over” the houses of the Jews and God
fearers, those who placed blood in the door post, when he was slaying the firstborn of Egypt. In Hebrew, it is known as Pesach, which is based on the  Hebrew root meaning “pass over”. The holiday is also referred to as Chag
he-Aviv (the Spring Festival), Chag ha-Matzoth (the Festival of Matzahs), and Zeman Herutenu (the Time of Our
Freedom).

Many of us know about the first Passover in Egypt and the last Passover of Jesus with His disciples but we kind of neglect many of its significance in relation to our faith.  Probably the most significant observance related to Passover that we fail to see is the removal of chametz (leaven) from the homes. The removal of the leaven is also a symbolic way of removing the“puffiness” (arrogance, pride) and ultimately the sins from our souls.  In many instances, the Bible equated leaven with sin (1 Cor 5:7-8, Luke 12:1)

The prohibition against leaven is beyond question.  Leaven in Hebrew literally means "sour." The term "leaven" refers to any fermenting product such as yeast or baking powder.  Another Hebrew word for leaven used in Exodus was sehore (Exo 13:7) which means“swelling”.  Eating of bread with leaven during the feast carried severe consequences,
as mandated by God in the Scripture (Exo 12:15; 13:7). All leaven or anything made with leaven are to be removed from the dwelling places should not to be found anywhere in the land (Deut 16:4).  Chametz includes anything made from the five major grains (wheat, rye, barley, oats and spelt). 

The process of cleaning the home of all chametz in preparation for Passover is an enormous task.  Most of them would start at least a month prior to start cleaning their homes not only with anything with leaven but everything that are undesirables and considered garbage. They would spend several days scrubbing everything down, going over the edges of their stoves and fridges and eventually the whole house. The spring cleaning practices was taken from this. After the cleaning is completed, the morning before the seder, a formal search of the house for chametz is undertaken, and any remaining chametz is burned.  For them, as they clean their houses of leaven and dirt, they also
prepare themselves spiritually as they approach the holy day.

These practices would give us a lot of lessons.  The  removal of leaven from among us is a  physical manifestation of spiritual truth.  Apostle Paul said in 1 Cor 5:7-8, “Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us: Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened [bread] of sincerity and truth.”

Some people would argue that practicing this is legalistic but is there anything unbiblical about this?  If we can learn something about these practices that will make our walk with God better, why not do it in the  context of our faith instead rather than completely reject it?  Are we sinning against God if we intentionally refrain from eating anything with leaven during the time of Passover/Unleavened Bread just as He commanded the Israelites in the Scripture(Ex. 12:14-20; 13:6-8; 23:15; 34:18;  Lev. 23:6; Deut. 16:3, 8)?  If we do not judge those brethren who came from catholic who won’t eat meat during the holy week, are we suppose to pass judgement to those who won’t eat leaven during the Passover?  Since we are doing our sping cleaning in time for the season, why not remove the leaven from among us both spiritually and physically in time for the season?  It is just a thought.
