And ye shall observe this thing [Passover] for an ordinance to thee and to thy sons for ever:.. And it shall come to pass, when your children shall say unto you, What mean ye by this service? that ye shall say, It is the sacrifice of the Lord 's Passover, who passed over the houses of the children of Israel in Egypt... (Exodus [Shemot] 12:24,26-27).

How Did Yeshua Fulfill the Passover?
The Feast of Passover (Pesach) was given by G-d to be a rehearsal (miqra) of the first coming of Yeshua. The Passover ceremony was observed in remembrance of the past and in preparation for the future. Many years after the Passover in Egypt, a person named John (Yochanan) the Baptist (Immerser), pointed to Yeshua and declared that He was the Lamb of G-d (John [Yochanan] 1:29). After John (Yochanan), a type of Elijah (Eliyahu) who would prepare the coming of Messiah, proclaimed Yeshua as the Lamb of G-d, Yeshua ministered for three-and-a-half years. At the end of that time, on the tenth of Nisan, the high priest marched out of the city of Jerusalem to Bethany where a lamb was to be slain. The lamb was led back into the city through streets lined with thousands of pilgrims singing the Hallel (Psalms [Tehillim] 113-118). The liturgy for Hoshanah Rabbah says that the Messiah will come to the Mount of Olives and weep over the city. This happened in Luke 19:41. The people also waved palm branches as Yeshua rode into the city on a donkey in fulfillment of Zechariah 9:9. Today, Nisan 10 is known as Palm Sunday in the non-Jewish community.
The lamb that was to be slain by the high priest was led into the temple (Beit HaMikdash) and put in a prominent place of display. Likewise, Yeshua the Lamb of G-d went on public display when He entered the temple (Beit HaMikdash) and spent four days there among the people, the Sadducees, the Pharisees, and the scribes, as the leaders asked Yeshua their hardest questions. Yeshua was questioned in front of the people for four days, showing Himself to be without spot or blemish, fulfilling Exodus (Shemot) 12:5.
On the fourteenth of Nisan, at the third hour of the day (9:00 a.m.), the high priest (Cohen HaGadol) took the lamb and ascended the altar so he could tie the lamb in place on the altar. At the same time on that day, Yeshua was tied to the tree on Mount Moriah (Mark 15:25). At the time of the evening sacrifice (3:00 p.m.) for Passover (Exodus [Shemot] 12:6), the high priest (Cohen HaGadol) ascended the altar, cut the throat of the lamb with a knife, and said the words, "It is finished." These are the exact words said after giving a peace offering to G-d. At this same time, Yeshua died, saying these exact words in John (Yochanan) 19:30. Yeshua died at exactly 3:00 p.m. (Matthew [Mattityahu] 27:45-46,50).
In Exodus (Shemot) 12:8-9, we are told the lamb was to be roasted before sundown. According to the tractate Pesahim in the Mishnah, the lamb was roasted on an upright pomegranate stick. This pomegranate stick is representative of the tree upon which Yeshua died. The lamb was to be gutted, and its intestines were to be removed and put over its head. Thus, the lamb is referred to as the "crowned sacrifice." This is a picture of Yeshua in (Psalm [Tehillim] 22:13-18).
Deuteronomy (Devarim) 16:16 says that all the congregation of Israel was required to be present at the feasts of Passover (Pesach), Weeks (Shavuot) or Pentecost, and Tabernacles (Sukkot). This explains why all were gathered to witness the death of Yeshua on the tree (Matthew [Mattityahu] 27:1-26).
The night of the fifteenth of Nisan, G-d commanded the people to eat the lamb with unleavened bread (matzah) and bitter herbs (maror), their sandals on their feet and their bags packed and on their backs (Exodus [Shemot] 12:6,8,11), for on this night they are to leave Egypt. Likewise, we are to be quick to accept Yeshua into our hearts and leave Egypt, which represents the sin and idolatry of this evil world.
The Conclusion of Passover ( Pesach)
In concluding our study of Passover ( Pesach ), we can see that the G-d of Israel gave Passover ( Pesach) to His people so we could understand the death of Yeshua on the tree during His first coming, as well as understand our personal spiritual salvation in Yeshua from Pharaoh and Egypt (who is liked to satan [ ha satan ] and the kingdom of sin and darkness). Furthermore, the historical Egyptian Passover was also given by the G-d of Israel so we could understand the future redemption of His people (both houses of Israel who are today called by the corporate names of Christianity and Judaism) in the end of days when they will return to the land of Israel (specifically, the mountains of Israel or the West Bank). This redemption will take place in the end of days prior to the coming of King Messiah ( Mashiach ). Because of the historical deliverance from the bondage of Egypt, our personal salvation in Yeshua as Messiah ( Mashiach ) and our future redemption from exile in the nations of the world and return to the land of Israel in the end of days, Passover ( Pesach ) has been given by the rabbis the appropriate title of the "Feast of our Freedom !!!".
