Meaning in one sentence
Why does God call Israel his firstborn son in Exodus 4:23? Discover the meaning of this verse and its connection to the tenth plague.
Context
This verse sits near the end of Moses’s calling at the burning bush. God has just given Moses signs to prove his commission, and now he tells him what to say to Pharaoh. The demand is simple: let Israel go so they can worship. But God also gives Moses the final warning, a threat that will become the tenth plague. The verse is God’s own summary of the whole conflict before it starts. It ties the fate of Pharaoh’s firstborn to the release of God’s firstborn son, the nation of Israel.
Key Words
The word firstborn (bekhor) carries weight throughout the Old Testament. It means the first to open the womb, the one who receives the double inheritance and the family’s leadership. When God calls Israel “my son, my firstborn,” he is claiming them as his own, with all the rights and protection that belong to the heir. Pharaoh is being told that Israel is not a slave people, they are the child of the King.
The verb serve (‘avad) is the same word used for worship. God does not just want Israel out of Egypt for freedom’s sake. He wants them free so they can serve him properly, through sacrifice and celebration, without Egypt’s interference. This is not a command to do labor; it is an invitation into relationship.
Kill (harag) is a blunt word for taking life. There is no softening here. God states plainly what will happen if Pharaoh refuses. The gravity of the warning matches the depth of the bond: the firstborn of Egypt will fall because the firstborn of God is being held.
How Christians Read This Verse
John Calvin read this verse as a call to perseverance. He wrote that God commands Moses to press the warning on Pharaoh even when the tyrant is desperate, so that Moses would not falter. Matthew Henry saw a principle of divine justice: “As men deal with God’s people, let them expect to be themselves dealt with.” The Cambridge Bible notes that the verse may have originally stood just before the tenth plague narrative, functioning as the climax of the whole series. Across traditions, readers agree that this verse shows God’s commitment to his people and the seriousness of opposing his purpose.
A common misunderstanding
Some read this verse and think God is cruel, killing children for a father’s choice. In fact, the threat comes after God has already sent nine plagues, each giving Pharaoh a chance to release Israel. The death of the firstborn is the final judgment, not a first response. It matches the crime: the firstborn of Egypt dies because the firstborn of God was enslaved. The warnings were clear and many.
Living This Out
You and I are not facing an Egyptian king. But we still face a choice: will we serve what owns us, or will we let God set us free to worship him? This verse asks you to see yourself as God sees you, his child, his firstborn. Not because you earned it, but because he says so. When you feel stuck in something that keeps you from serving him freely, remember that God considers you worth fighting for. It may take time, but he does not give up on his children.
Main takeaway: God calls Israel his firstborn son and will go to any length, even severe judgment, to free them for worship, because he will not abandon his own.
For Families
For ages 5, 8
God told Pharaoh to let His people go because they were His special children. When Pharaoh said no, God warned that something very hard would happen.
For ages 9, 12
God called Israel His “firstborn son” to show His deep love for them and His right to set them free. But Pharaoh refused again and again.
