Exodus 4:22-23

And thou shalt say unto Pharaoh, Thus saith the Lord, Israel is my son, even my firstborn: And I say unto thee, Let my son go, that he may serve me: and if thou refuse to let him go, behold, I will slay thy son, even thy firstborn.

This is a very weighty word, because the Lord tells Pharaoh exactly how he is to understand the issue. Israel is not merely a labor force. Israel is not simply a political problem. Israel is not just one more people group living inside the borders of Egypt. God says, “Israel is my son, even my firstborn.” That changes everything. Pharaoh was not merely oppressing slaves. He was laying hands on that which God claimed as His own.

That is why the warning is so severe. “Let my son go, that he may serve me.” This was never only about freedom from harsh conditions. It was about relationship and rightful belonging. God was calling for the release of His son so that His son might serve Him. Pharaoh was standing in the way of something sacred. He was refusing to release what belonged to the Lord. And because of that, the message carried the death penalty. If Pharaoh persisted in holding God’s firstborn, then Pharaoh’s own firstborn would die. The judgment would fit the crime. The one who refused to release the son of God would feel the loss of his own son.

That tells us plainly that God is not casual about sin. Men may treat rebellion as something light, manageable, and excusable, but the Lord does not. Sin is not small because it is committed against an infinitely holy God. Pharaoh may have imagined this was merely a contest of power, a political standoff between a ruler and an agitator. But God makes it clear that it is far more serious than that. Pharaoh’s resistance was not merely against Moses. It was against the Lord Himself.

And yet there is something deeper here too. At first glance, the passage speaks of two sons. There is Israel, God’s firstborn, and there is Pharaoh’s firstborn, who will die if Pharaoh refuses to obey. But in the larger sweep of Scripture, there is a third Son in view, and that is where the passage begins to open up in a fuller way. There is the true and eternal Son of God, Jesus Christ.

Israel is called God’s son in a national and covenant sense. Pharaoh’s son stands under the warning of judgment. But Jesus is the beloved Son in a way no one else is. He is not merely called a son. He is the Son. And what is so astonishing is that in order to bring many sons unto glory, the true Son would one day place Himself under judgment. The firstborn of Egypt would die because of Pharaoh’s hardness. But the only begotten Son of God would die so that hardened sinners might be forgiven.

That is where this passage starts to shine with gospel light.

God says, “Let my son go, that he may serve me.” Ultimately, that is what redemption is all about. God is claiming a people for Himself. He is delivering them from bondage so that they might belong to Him and serve Him. But the deepest way He would do that would not be merely through plagues in Egypt. It would be through the Cross. There the true Son would stand in the place of the guilty, bearing judgment so that those who were in bondage might be set free.

So this warning to Pharaoh is severe, and it should be. God is deadly serious about sin. But even in the severity, there is a deeper redemptive pattern beginning to show. God loves His son. God will not abandon His son. God will act to bring His son out. And in the fullness of time, He will do it through Another Son, a greater Son, the One who would not simply confront a Pharaoh, but would crush sin, death, and hell itself.

That makes these verses both solemn and precious. Solemn, because they remind us that resisting God is no light thing. Precious, because they remind us that God is committed to redeeming a people for Himself. Pharaoh heard the warning and hardened his heart. But the greater story moves toward the day when the Father would send His own Son, and through that Son, bondage would finally be broken for all who believe.
