Exodus 4:25 describes Zipporah, Moses’ wife, acting quickly to save her husband’s life by circumcising their son with a flint knife. The verse is strange on first reading, but its meaning becomes clear once you see what was at stake: Moses had neglected the covenant sign God gave to Abraham, and the Lord had confronted him on the road to Egypt. The speaker is the narrator describing Zipporah’s act, and her words are addressed to Moses, though they are spoken over the boy’s body.
Then Zipporah took a flint, and cut off the foreskin of her son, and cast it at his feet; and she said, “Surely you are a bridegroom of blood to me.”

What Exodus 4:25 Means
The verse begins with Zipporah taking a flint, a sharp stone blade, and cutting off her son’s foreskin. Circumcision was the sign of the covenant God had established with Abraham, a mark that belonged to every male in the household of Israel. Moses had apparently not circumcised this son, and that failure put the whole mission at risk. Zipporah acts because she understands the seriousness of the moment, even if the text gives no full explanation of her reasoning.
Her words, “Surely you are a bridegroom of blood to me,” are the most debated part of the verse. Most readers take her to mean that the blood of circumcision has bound her family to God’s covenant in a new way, and that the blood spared Moses. The verse does not promise that obedience always comes with a clear explanation, and it does not present Zipporah as a model of perfect piety. It simply shows God’s holiness and the cost of neglecting his commands.
The Context of Exodus 4:25
Exodus is traditionally attributed to Moses and tells the story of Israel’s deliverance from Egypt. Our verse sits in the middle of God’s commissioning of Moses, right after the Lord tells him to say that Israel is his firstborn son and that Pharaoh will lose his own firstborn if he refuses to let them go. The readers would have been Israelites who knew the covenant sign well and would have felt the weight of its neglect.
Read in context, verses 24 through 26 show God meeting Moses at a lodging place and threatening him, then Zipporah’s act turns the danger aside. The next verses show Aaron going out to meet Moses, so the account moves quickly back to the mission. The passage teaches that God takes his covenant seriously even when his chosen servant is the one who has fallen short.
Key Phrases in Exodus 4:25
Genesis 17:10
This is my covenant, which you shall keep, between me and you and your offspring after you. Every male among you shall be circumcised.
(WEB)
This verse records God’s original command to Abraham to circumcise every male as the sign of the covenant. Reading it alongside Exodus 4:25 shows that Moses’ failure was a failure to honor a commandment already long established. It explains why the covenant sign mattered so much to God and to the household of Israel.
Exodus 4:22
You shall tell Pharaoh, ‘The LORD says, Israel is my son, my firstborn…
(WEB)
This verse places Israel as God’s firstborn son, the relationship that frames the entire mission Moses is undertaking. Seeing this identity helps explain why the threat to Moses carried such weight. The covenant sign was tied to this sonship, and both reveal God’s deep commitment to his people.
A Short Prayer From Exodus 4:25
Lord, you are holy, and your covenant is not a casual thing to me. Forgive me for the ways I have delayed what you have clearly asked of me. Give me the willingness of Zipporah to act quickly when your word is plain, even when I feel unready or unsure. Help me to trust that you honor obedience and that you are faithful to those who belong to you. Amen.
