What does Exodus 12:4 mean?
Moses and Aaron (Exodus 12:1) are explaining the Lord's instructions for the first Passover (Exodus 12:2–3). These include a detailed process for sacrifice of a lamb. Here, God explains how families can join when a single lamb is too large for a family to eat (Exodus 12:10). This probably also applied when a family could not afford an appropriate sacrifice (Exodus 12:5).These instructions are part of how Israel will be spared from God's wrath on Egypt (Exodus 11:4–6). Following these steps will cause the Lord to "pass over" that home in peace (Exodus 12:13). They also create a system of symbols and traditions supporting the ministry of the ultimate Passover Lamb, Jesus Christ (John 1:29, 36; Acts 8:32; 1 Corinthians 5:7; 1 Peter 1:19). His sacrificial death at Passover (Matthew 26:2) would fulfill the prophecies and promises established through Israel's patriarchs (Genesis 12:7; 15:5, 13–14; 17:5–6) and developed through the nation's experiences in Egypt (Hebrews 8:8–10; 10:11–14).
