Exodus 4:23
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.
Exodus 4:23 (KJV)
Context
This verse stands at the end of God’s message to Moses at the burning bush. God sends Moses to Pharaoh with a clear demand: release Israel from slavery. The people of Israel had suffered in Egypt for many years, and God had heard their cries. He chose Moses to lead them out, even though Moses felt weak and afraid. God answered Moses’ fears with promises of presence and power.
The words of Exodus 4:23 are part of a larger speech. In the verse just before, God calls Israel “my son, even my firstborn” (Exodus 4:22). That title shows the special bond between God and His people. Now God tells Moses to repeat this message to Pharaoh, so that the king of Egypt will know exactly who is speaking and what is required.
Meaning
When God says, “Let my son go, that he may serve me,” the word “serve” carries the sense of worship and obedient service. The Hebrew term translated “serve” (abad) implies not just labor but devoted worship. Israel’s freedom was not an end in itself. They were set free so they could worship God in the place He had chosen. Their release from bondage had a purpose: to serve and honor the Lord.
The warning that follows is direct and severe. If Pharaoh refuses, God will slay Pharaoh’s firstborn son. This was not an empty threat or a random punishment. It was the just consequence of Pharaoh’s stubborn opposition to God’s command. The king of Egypt had treated God’s firstborn son, Israel, with cruelty. Now God would act against Egypt’s firstborn.
Biblical connections
This warning points forward to the tenth plague, recorded in Exodus 12:29, when the Lord struck down every firstborn in Egypt. That event broke Pharaoh’s resistance and led to Israel’s departure. The connection is direct: what God announced in Exodus 4:23 came to pass exactly as He said.
The verse also foreshadows a greater deliverance. Israel, God’s son, was spared through the blood of the Passover lamb. In the New Testament, Christ is called the firstborn and the Lamb of God. He was slain so that God’s children might be freed from sin and serve Him. The pattern of judgment and redemption in Exodus finds its fullest meaning in Jesus.
Application
God still claims His people for Himself. He calls each believer to leave the bondage of sin and to serve Him with a willing heart. The command “Let my son go, that he may serve me” reminds us that freedom in Christ is not freedom to do as we please. It is freedom to worship and obey God.
This verse also warns us about the danger of a hard heart. Pharaoh refused to listen, and his refusal brought ruin. When God speaks through His Word, the wise response is humble obedience. Resistance to God’s will does not change His purposes; it only brings judgment.
Reflection
God’s power over rulers and nations is clear in this verse. Pharaoh was the most powerful man in Egypt, yet he could not stand against the word of the Lord. We can trust that God’s plans will prevail, even when human authority seems overwhelming.
God’s love for His people is equally clear. He called Israel “my son” and acted to set them free. He has done the same for us through Christ. Our response should be gratitude and wholehearted service, knowing that we belong to Him.
