What does Exodus 13:11 mean?
This begins the Lord's instructions about what it means to consecrate all firstborn to the Lord (Exodus 13:1–2). That requirement would begin once the Israelites were established in Canaan. The land promised to Abraham (Genesis 12:6–7; 15:13–21) was then occupied by many cultures, all of which fall under the description of "Canaanite." This territory was part of numerous guarantees given to Israel's ancestors (Genesis 17:8; 48:3–4; 50:24). Israel was expected to take this territory both as a fulfillment of their destiny (Deuteronomy 7:6; 14:2) and as God's instrument of punishment against the Canaanite people for their depraved evils (Genesis 15:16; Deuteronomy 9:4).The first male born to any female—person or animal—would be considered God's (Exodus 13:12). People, as well as those animals that were to be kept alive, were to be "redeemed" with the sacrifice of a lamb (Exodus 13:13). This would serve as a reminder of how God rescued the people from slavery in Egypt (Exodus 12:40–41; 13:14).
