The Lord said to Moses and Aaron in Egypt, “This month is to be for you the first month, the first month of your year. Tell the whole community of Israel that on the tenth day of this month each man is to take a lamb for his family, one for each household. If any household is too small for a whole lamb, they must share one with their nearest neighbor, having taken into account the number of people there are. You are to determine the amount of lamb needed in accordance with what each person will eat. The animals you choose must be year-old males without defect, and you may take them from the sheep or the goats. Take care of them until the fourteenth day of the month, when all the members of the community of Israel must slaughter them at twilight. Then they are to take some of the blood and put it on the sides and tops of the door frames of the houses where they eat the lambs. That same night they are to eat the meat roasted over the fire, along with bitter herbs, and bread made without yeast.” –Exodus 12:1-8
You may read Exodus 12-13:16 here: Bible Gateway.
God instituted the holiday of Passover. So begins God’s story of redemption, the central theme of the Bible. Redemption means “to buy back” or “to save from captivity by paying a ransom.” A slave could be purchased by offering an equivalent or superior slave in exchange. This is a picture of how God chose to buy us back from captivity to sin and spiritual death. But God didn’t purchase us with a superior slave. Instead, He offered His perfect sinless Son so we could live with Him forever.
In Old Testament times, God accepted symbolic offerings: an animal’s life for the sinner’s life.
For the Israelites to be spared from the death plague, a lamb without defects had to be killed. God commanded its blood be placed on the door frames of each home. The innocent lamb was a substitute for the person who would have died in this final plague—another picture, or symbol, of Christ being our sacrificial Lamb.
God didn’t spare the firstborn of the Israelites because they were more righteous than the Egyptians, but rather by His grace alone. God also made provision for non-Israelites to participate in Passover if they acknowledged their faith in the Abrahamic Covenant, as demonstrated through circumcision (Genesis 17:9-14; Exodus 12:48-49). Since a large number of non-Israelites left Egypt with Israel (v 38), It’s likely that many Egyptians converted as a result of the plagues and were spared death through Passover’s provision.
The Passover is proof of God’s possession of Israel. The firstborn of Israel belonged to God as a result of the Passover, and all of Israel was God’s possession as a result of the Exodus. All of the commandments and requirements which God placed upon the Israelites were predicated upon the fact that they were a people who belonged to Him.” – Layman’s Bible Commentary
Like the redemption of the firstborn and the Feast of Unleavened Bread, the Passover was to become a permanent part of Israel’s religious liturgy (12:24-25). The Passover not only memorializes God’s mighty hand in Israel’s deliverance from slavery, but also serves as instruction and a reminder for Israel’s future generations (12:26-27; 13:8, 14-16).
Believers today also experience a deliverance and restoration to God. When Jesus came and ushered in the New Covenant, He made repeated animal sacrifice no longer necessary. His sacrificial death on the cross enables the believer’s redemption—deliverance from spiritual death and slavery to sin—through belief and trust in Him. By taking the penalty we deserve, Christ’s blood sacrifice covers us, sparing us from the spiritual death we deserve because of our sin (Titus 2:14; Hebrews 9:13-15, 23-26).
I found the following 38 minute video, “Christ in the Passover”, really interesting and insightful. David Brickner, Executive Director of Jews for Jesus, links the ancient Festival of Redemption and Christ as the Lamb of God in a meaningful visual sermon demonstration. If you have time, I encourage you to view it, especially as Passover draws closer. . . . Blessings!
