The concept of the redemption of the firstborn holds significant weight in understanding the imagery of lambs in Scripture, particularly as it relates to Jesus Christ being called the Lamb in the book of Revelation. In Exodus 13, God declares His claim on all firstborns, both of man and beast, establishing the law of the firstborn even before Israel reached the Red Sea. This law, given among the very first instructions to His newly purchased nation, underscores the importance of redeeming the firstborn, a matter of great significance to God. He claimed Israel as His firstborn and redeemed her from Pharaoh, requiring the Israelites to redeem every firstborn male with a lamb, symbolizing the exchange of one life for another due to a prior claim of ownership. This usage of lambs for redemption, rather than atonement for sin, aligns more closely with the depiction of the Lamb in Revelation. Unlike sin offerings which address atonement, redemptions deal with ownership, as seen when God redeemed His people from Pharaoh to fulfill His promises. The pattern of redemption is evident in Abraham's life when God required him to sacrifice his firstborn, Isaac, and provided a ram for redemption due to Abraham's willingness to obey. Similarly, in the broader context of God's plan, redemption extends beyond forgiveness of sins to a future liberation from the power of the flesh, enabling believers to manifest the complete image and likeness of their Creator. Thus, the title of Lamb in Revelation evokes this profound theme of redemption and ownership, highlighting Jesus Christ's role in buying back and rescuing His people from bondage.

God's Plan of salvation for mankind is revealed through His commanded holy days, with the Passover symbolizing the initial steps toward communion with Him and His Son, Jesus Christ. The Passover lamb, chosen and killed by the Israelites, provided blood to mark their doorposts, serving as a sign for the Death Angel to pass over their homes, sparing their firstborn while the firstborn of Egypt perished. This act of marking the doorposts with blood represents not a covering for sin but the life of the lamb given to redeem or buy back those within the house. Scripture frequently speaks of the Passover in terms of purchasing or redeeming the children of Israel from Pharaoh, rather than forgiveness or atonement. Thus, the festival focuses on the ongoing fellowship God initiates with His called-out people, becoming a solemn yet joyful celebration of the peace and well-being we have in Christ.

Brethren, the subject of the Firstborn and their Redemption is a vital scriptural technicality that we must understand deeply, especially in relation to the Days of Unleavened Bread. In Exodus 13:1-2, the Lord spoke to Moses, saying, "Consecrate to Me all the firstborn, whatever opens the womb among the children of Israel, both of man and beast; it is Mine." From this moment, God claimed the firstborn as His own, marking a significant act of sanctification following the destruction of the firstborn in Egypt. While He took the lives of Egypt's firstborn, He set apart Israel's firstborn for Himself. This consecration ties directly to the command to eat unleavened bread, as seen in Exodus 13:3, where Moses instructs the people to remember the day they left Egypt, the house of bondage, for by the strength of His hand, the Lord brought them out. The eating of unleavened bread serves as a reminder not merely of coming out of sin, but primarily of what the Lord did in delivering His people. It reinforces the truth that their freedom was not by their own effort, but by His mighty intervention. Further, in Exodus 13:11-16, God elaborates on the redemption of the firstborn. Every firstborn male animal that opens the womb is to be set apart to the Lord, and for a donkey, it must be redeemed with a lamb, or its neck broken if not redeemed. Likewise, every firstborn son among the Israelites must be redeemed. This act of redemption is explained to future generations as a memorial of how the Lord, by strength of hand, brought them out of Egypt after striking down the firstborn of both man and beast in that land. It serves as a sign and a reminder of His power and purpose in their deliverance. In Numbers 3:9-13, we see a significant transfer of responsibility. The Lord declares that He has taken the Levites from among the children of Israel in place of every firstborn who opens the womb. The Levites are set apart as His, to serve in the priesthood, replacing the firstborn who were initially claimed as His after the events in Egypt. This shift underscores that the firstborn belong to Him, sanctified on the day He struck Egypt's firstborn, and now their role is fulfilled through the Levites' service. Brethren, the redemption of the firstborn is no minor detail in God's purpose. It is intricately connected to the Days of Unleavened Bread, reminding us that our coming out of bondage—whether from Egypt or sin—is primarily the work of God overcoming the world and its forces. We must keep this in focus, ensuring that we do not overlook the Father's central role in our salvation, for it is by His initiative and strength that we are set free.
