Exodus 4:23 is God’s message to Pharaoh through Moses. God announces that Israel is his firstborn son, commands Pharaoh to release that son so he can worship him, and warns that Pharaoh’s refusal will bring the death of Pharaoh’s own firstborn. The verse is spoken by the LORD, relayed by Moses, and directed to the king of Egypt.
And I have said to you, “Let my son go, that he may serve me”; and you have refused to let him go. Behold, I will kill your son, your firstborn.’”

What Exodus 4:23 Means
The phrase “Let my son go, that he may serve me” is a demand for release with a purpose. Israel is not being freed merely to leave Egypt; they are being freed so they can serve God. The word “serve” here carries the sense of worship and devoted service to the LORD, not simply labor. Pharaoh is told that his refusal has already been noticed, because God says, “you have refused to let him go.”
The last sentence is a judgment, not a comfort. “Behold, I will kill your son, your firstborn” announces the tenth plague, the death of the firstborn in Egypt, which God later carries out. The verse does not promise Israel an easy road out of bondage. It shows that God takes his people’s freedom seriously and will act against any power that stands in the way. It also does not teach that God treats every family the same way; it is a specific judgment tied to a specific moment of confrontation.
The Context of Exodus 4:23
Exodus is traditionally attributed to Moses and tells how God rescued the descendants of Jacob from slavery in Egypt and formed them into a nation at Sinai. The book was written for Israel, the people who had lived under Egyptian oppression and who needed to understand who their God was and what he intended for them. Chapter 4 is the moment God sends Moses back to Egypt with a commission to speak for him.
Verses 20 through 26 frame the verse as part of a larger scene. Moses sets out with his wife and sons, God gives him instructions for dealing with Pharaoh, and the verse appears as the words Moses is to deliver. Immediately afterward, at a lodging place, the LORD meets Moses in a frightening encounter, and Zipporah circumcises their son. Reading the verse alongside these events shows that God’s claim on Israel and his claim on Moses’s own household are bound together, and that covenant obedience matters within the family as well as before Pharaoh.

5 Now therefore, if you will indeed obey my voice, and keep my covenant, then you shall be my own possession from among all peoples; for all the earth is mine; 6 and you shall be to me a kingdom of priests, and a holy nation.’ These are the words which you shall speak to the children of Israel.”

These verses describe Israel as God’s treasured possession and a kingdom of priests, the fuller meaning of the calling introduced in chapter 4. Reading them shows that the freedom promised in the earlier verse leads to a people set apart for God’s purposes.
Romans 8:21
That the creation itself also will be delivered from the bondage of decay into the liberty of the glory of the children of God.

Paul uses the theme of liberation from bondage and the glorious freedom of God’s children to speak of the whole creation. The verse helps readers see that the exodus pattern of release from captivity into the life God intends runs throughout the story of redemption.
A Short Prayer From Exodus 4:23
Lord, you have called your people your own and set them free for your service. I confess that I sometimes cling to things that hold me back from serving you fully. Loosen my grip on whatever keeps me from you, and help me see the freedom you offer as a freedom for devotion and worship. Be near to those I love who are still caught in bondage, and draw them to yourself. Thank you for claiming me as your child. Amen.
