Exodus 13:15
“When Pharaoh stubbornly refused to let us go, Yahweh killed all the firstborn in the land of Egypt, both the firstborn of man, and the firstborn of livestock. Therefore I sacrifice to Yahweh all that opens the womb, being males; but all the firstborn of my sons I redeem.’”
What does Exodus 13:15 mean?
This passage reflects the practice that emerged after the tenth plague, when God passed over the homes of Israelites while the firstborn of Egypt died. The law described here established a lasting memorial: the firstborn males of flocks would be sacrificed to God, while the firstborn sons of families would be "redeemed," or bought back, with a payment instead of being given to God's service. The underlying idea is that the Israelites owed everything to God for their liberation—their very survival came through divine intervention. By dedicating the firstborn to God (whether through sacrifice or redemption payment), they were acknowledging that their freedom and their future belonged to him. This wasn't a harsh demand but a way of keeping alive the memory of what God had done and expressing gratitude through regular, costly acts of worship and obedience.
