Introduction:
Passover, known as Pesach in Hebrew, is one of the most significant feasts in the Jewish calendar and holds profound theological importance in Christianity. It commemorates the Israelites' deliverance from slavery in Egypt, as recorded in the Book of Exodus. This event is foundational to understanding God's redemptive plan and is a precursor to the Christian celebration of Easter.

Biblical Account:
The narrative of Passover is primarily found in Exodus 12. God commands Moses and Aaron to instruct the Israelites to take a lamb without blemish, slaughter it, and apply its blood to the doorposts and lintels of their homes. This act would serve as a sign for the Lord to "pass over" their houses during the final plague—the death of the firstborn in Egypt. Exodus 12:13 states, "The blood on the houses where you are staying will distinguish them; when I see the blood, I will pass over you. No plague will fall on you to destroy you when I strike the land of Egypt."

Theological Significance:
Passover is a profound demonstration of God's power and faithfulness. It marks the beginning of the Israelites' journey to freedom and the establishment of a covenant relationship with God. The event underscores themes of sacrifice, redemption, and divine deliverance. The lamb's blood, which spared the Israelites from death, prefigures the sacrificial death of Jesus Christ, the "Lamb of God," who takes away the sin of the world (John 1:29).

Passover in Jewish Tradition:
In Jewish tradition, Passover is celebrated with a Seder meal, which includes the retelling of the Exodus account, the eating of unleavened bread (matzah), and the consumption of symbolic foods. The Seder is a time of remembrance and teaching, ensuring that each generation understands the significance of God's deliverance.

Passover and the New Testament:
The New Testament draws a direct connection between Passover and the crucifixion of Jesus Christ. The Last Supper, which Jesus shared with His disciples, was a Passover meal. During this meal, Jesus instituted the Lord's Supper, saying, "This is My body, given for you; do this in remembrance of Me" (Luke 22:19). The Apostle Paul further emphasizes this connection in 1 Corinthians 5:7 , stating, "For Christ, our Passover lamb, has been sacrificed."

Christian Observance:
For Christians, Passover is fulfilled in the death and resurrection of Jesus Christ. The themes of liberation and redemption are central to the Easter celebration. While some Christian denominations observe Passover in conjunction with Easter, others focus on the spiritual significance of Christ's sacrifice as the ultimate Passover Lamb.

Conclusion:
Passover remains a pivotal event in both Jewish and Christian traditions. It serves as a powerful reminder of God's deliverance and the foreshadowing of the ultimate redemption through Jesus Christ. The observance of Passover continues to be a time of reflection, gratitude, and hope for believers around the world.
