What does Exodus 12:26 mean?
Moses is telling Israel that they will be freed from Egypt (Exodus 12:13, 41) and will eventually come to the land which was promised to Abraham (Genesis 15:13–14, 18–21), Isaac (Genesis 21:3; 26:1–5), and Jacob (Genesis 25:26; 28:10–17; 50:25). The Lord has given instructions about certain festivals which the nation must observe to remember these events (Exodus 12:14, 17–20).When these traditions are followed, the children of future generations will ask about them. The specific nature of the rituals would invite questions. Why did it have to be a flawless, one-year-old lamb (Exodus 12:5–6, 13)? Why must they eat unleavened bread (Exodus 12:8, 39)? The people must be ready to explain all that the Lord has done for His people. They should also be prepared to give a precise answer (Exodus 12:27).
These words offer hope of a future to the people of Israel. In contrast, the Egyptians are about to be devastated by the loss of their firstborn (Exodus 11:4–6). God's laws and commands in the Old Testament invested children with enormous value (Leviticus 18:21; 20:2–5). Knowing the truth of what God had done was part of teaching the next generation the value of honoring the Lord (Deuteronomy 4:10; 11:18–21; 12:25; 29:29).
