Exodus 34:20
But the firstling of an Asse thou shalt redeeme with a lambe: and if thou redeeme him not, then shalt thou breake his necke. All the first borne of thy sonnes thou shalt redeeme: and none shall appeare before me empty. Exodus 34:20 (KJV)
This command is given as part of God’s broader set of laws to the Israelites while they wander in the wilderness after the exodus. It underscores the principle that the firstborn—whether animal or human—belongs to the Lord and must be set apart.
Redemption of the Firstborn Ass: In ancient Israel the firstborn donkey was regarded as God’s property. The law required the owner to redeem the animal by offering a lamb in its place. This act served as a tangible reminder of God’s deliverance when He spared the Israelite firstborns during the tenth plague while the Egyptians’ firstborns perished (see Exodus 13:11‑16).
Consequences of Non‑Redemption: If the owner failed to redeem the firstborn donkey, the command was to break its neck. Though severe, the penalty highlighted the seriousness of obedience and the sanctity of that which is devoted to God.
Redemption of the Firstborn Sons: The same principle applied to the firstborn sons of Israel. Their redemption involved a payment—traditionally five shekels of silver as recorded in Numbers 18:15‑16—and, in some cases, a sacrificial offering. This practice acknowledged that the firstborn were consecrated to God and required a substitute offering.
The passage teaches several enduring principles. First, ownership and sanctity: everything, including the firstborn, ultimately belongs to God, calling believers to consecrate the best of what they have. Second, redemption and sacrifice: the lamb offered for the donkey points forward to the ultimate substitution of Christ, the Lamb of God, who redeems humanity from sin. Third, obedience and consequences: the harsh penalty for neglecting the command serves as a reminder that disobedience carries real cost. Finally, gratitude and worship: the phrase “none shall appear before me empty” urges the people to approach God with offerings and thankfulness, reflecting a heart of gratitude even though the verse itself does not mandate a specific offering. Together, these teachings reinforce a lifestyle of reverence, dedication, and thank‑giving toward the One who claims all firstfruits.
