Zipporah and the Bridegroom of Blood
Thesis The strange story of Zipporah and the bridegroom of blood in Exodus 4:24-26 is not about God threatening Moses but about God threatening Gershom for not being circumcised, and Zipporah's act formally brings him into the covenant people, illustrating that God assembles a team around Moses for the mission ahead and does not call us to serve him alone.
The shape of the argument
43 units across exposition, application, illustration, theological claim, and conclusion. The pastor's argument is built from these moving parts.
- cultural reference · unit #24 — Chris illustrates the narrative function of Exodus 4 by comparing it to The Fellowship of the Ring—both texts are assembling a team. The story isn't about the climactic event but about gathering the people who will accomplish it.
- Heiser's interpretation of Exodus 4:24-26, while acknowledging the passage's difficulty, is flawed because it relies on unwarranted assumptions. unit #6
- James B. Jordan's treatment of Exodus 4:24-26 is superior because it is historically comprehensive and contextually grounded. unit #7
- The Zipporah story is embedded in a larger narrative about God distinguishing between firstborn sons he claims and firstborn sons he judges. unit #11
- Gershom, Moses' firstborn son, had not been circumcised, which is a violation of the Abrahamic covenant. unit #12
- God was threatening Gershom, not Moses, because threatening Moses would contradict God's demonstrated patience and consistency of character. unit #15
- The text's plain statement that God sought to put him to death rules out the interpretation that God was merely bluffing, and Gershom as the target coheres with the firstborn son theme. unit #16
- Zipporah's circumcision of Gershom formally brings him into covenant membership, 'marrying' him to God's people through the sign of circumcision. unit #19
- God threatens Gershom to prevent an uncircumcised person from entering the covenant community, and Zipporah's act of applying blood marks him as one of God's people, analogous to the Passover doorposts. unit #22
- Exodus 4:18-31 functions as a team assembly narrative, and the Zipporah story provides Gershom's backstory—his formal entry into the covenant people. unit #25
- The Levites' prophesied violence explains Moses' temper and reveals that the priestly tribe functioned as God's avengers. unit #34
- The Levites, including Aaron, were among the fiercest men in Israel, not merely ceremonial priests. unit #37
- The Zipporah story illustrates that God brings people onto the team for his mission—he does not call us to serve alone. unit #39
"I dare you not to bore me with the Bible" — Dr. Michael Heiser (unit #5)
"Moses encounter with God in Exodus 4:24-26 is arguably one of the strangest and most confusing events recorded in the Bible" — Michael Heiser (unit #6)
"You and the people will certainly wear yourselves out, for the thing is too heavy for you. You are not able to do it alone. Now, obey my voice. I will give you advice, and God be with you. You shall represent the people before God and bring their cases to God. And you shall warn them about the statutes and laws and make them know the way in which they must walk and what they must do. Moreover, look for men, for able men from all the people, men who fear God, who are trustworthy and hate a bribe, and place such men over the people as chiefs of thousands of hundreds of 50s and tens, and let them judge the people at all times. Every great matter they shall bring to you. But any small matter they shall decide among themselves, so it will be easier for you, and they will bear the burden with you. If you do this, God will direct you and you will be able to endure. And all this people will also go to their place in peace." — Jethro (unit #28)
"prophet, priest and king" — John Calvin (unit #32)
"Simeon and Levi are brothers. Weapons of violence are their swords. Let my soul come not into their council. O my glory. Be not joined to their company. For in their anger they killed men, and in their willfulness they hamstrung oxen. Cursed be their anger, for it is fierce, and their wrath for it is cruel. I will divide them in Jacob and scatter them in Israel." — Jacob (unit #33)
"Put your sword on your side, each of you, and go to and fro from gate to gate throughout the camp. And each of you kill his brother and companion and his neighbor." — Moses (unit #36)
"I thank my God in all my remembrance of you always, in every prayer of mine, in every prayer of mine, for you all making my prayer with joy because of your partnership in the Gospel from the first day until now." — Paul (unit #41)

0 · Chris opens by framing the podcast as an auxiliary teaching on a difficult passage in Exodus 4 that he does not want to address during the Sunday sermon
Greetings and salutations. Welcome, welcome, welcome to the Providence Podcast. My name is Chris Oswald, senior pastor at Providence Community Church. We are going to dabble in Exodus chapter 4 today. That's where we will be headed this Sunday for the upcoming sermon on June 9th. I believe it is Exodus chapter four, and there's a particular part of Exodus chapter four that I really don't want to slow down to talk about during the sermon. So I thought, well, let's go ahead and hit it right now via a podcast.
1 · Chris recaps Exodus 3, emphasizing Moses' objections rooted in insufficiency and God's answers rooted in his promise to be with Moses
Now, if you'll remember, Exodus chapter three, we looked at it last week. We looked at it the week before is the commissioning of Moses. And we saw an interplay between God and Moses. Moses bringing up five distinct objections that all have to do with his insufficiency and the difficulty of the task. And then God bringing five answers, all of which have to do with his promise to be with Moses and to bless his efforts, and so on and so forth. The conversation ends when God tells Moses he won't have to do it alone. He will go back to Egypt and find Aaron, his brother, waiting for him. Aaron is, the text says, a good talker. And so Aaron will be glad to see Moses. And when he sees Moses, he will join the team and together they will go to Pharaoh's household and communicate the message that God has for them.
2 · Chris introduces the specific passage under consideration—the two-verse story of Zipporah and the bridegroom of blood—and makes a humorous aside about avoiding inappropriate wordplay
Now we're going to talk about this particular moment in Exodus chapter 4. And the heading probably in your Bible would be something like the bridegroom of blood or something like that. Now, this is a two verse story that takes place after Moses leaves the house of Jethro, his father in law, along with his wife and his two grown sons. We would assume they're grown just based on how long Moses had been married to Zipporah, his wife. And that was 40 years. And just, you know, Moses is 80 years old at this point, so we're assuming that piece of it. But I think, you know for good reason. And so we're going to talk about this little tiny story takes place in two verses that you might call Zipporah, circumcision and the bridegroom of blood. Now, before I get into this, I'm going to tell you that I will manfully resist any jokes related to zippers and circumcision. That's my promise to you in this podcast. I will not go there.
3 · Chris reads Exodus 4:18-23 aloud, pausing to note that Moses' stated reason for returning to Egypt (to see if his brothers are alive) suggests he is hedging and not yet fully convinced
All right, let me get into this story. Let's start by reading verse 18. This is sort of after Moses has agreed to go and do what God has called him to Do. It says then that Moses went back. This is verse 18 of chapter 4. Moses went back to Jethro, his father in law, and said to him, please let me go back to my brothers in Egypt to see whether they are still alive. And Jethro said to Moses, go in peace. Let me pause there and suggest to you that already we're seeing that Moses is not quite still yet convinced. He. He is, he is not communicating as far as we can see to Jethro that he had encountered God in the burning bush. He had not in is not discussing his particular mission. He simply says, let me go back to my brothers in Egypt to see whether they are still alive. So I think he's probably hedging his bets a bit. We might talk about that a bit more on Sunday. And Jethro said to Moses, go in peace. And the Lord said to Moses in Midian, go back to Egypt, for all the men who were seeking your life are dead. All the men who are seeking your life are dead. So Moses took his wife and his sons and had them ride on a donkey and went back to the land of Egypt. And Moses took the staff of God in his hand. The staff was just Moses staff, but now it's become the staff of God. Moses took the staff of God in his hand. And the Lord said to Moses, when do you go back to Egypt? See that you do before Pharaoh all the miracles that I have put in your power. But I will harden his heart so that he will not let the people go. Then you shall say to Pharaoh, Thus says the Lord Israel is my firstborn. And I say to you, let my son go, that he may serve me. If you refuse to let him go, behold, I will kill your firstborn sons. That's Exodus 4:18 23.
4 · Chris reads Exodus 4:24-26, the core text under examination, and explicitly labels it as strange
Now in verse 24, we come to the strange part. At a lodging place on the way, the Lord met him and sought to put him to death. Then Zipporah took a flint and cut off her son's foreskin and touched Moses feet with it and said, surely you are a bridegroom of blood to me. So he let him alone. It was then that she said, a bridegroom of blood because of the circumcision. That's a very strange passage.
5 · Chris transitions into a brief survey of interpretive approaches by citing Michael Heiser's book, which categorizes this passage as both weird and important
Dr. Michael Heiser wrote a book called I dare you not to bore me with the Bible. And it's a book largely comprised of what Heizer says are weird but important Bible stories. And he includes this story in that book.

5-day reading plan
This week we follow the arc of God's covenant faithfulness: from the binding nature of the Abrahamic covenant itself, through God's patient discrimination between those who belong to His people and those who do not, to the gospel's call to labor together in Christ's mission as a gift of grace.
Genesis 17 establishes that circumcision is not optional—it is the covenant obligation God demands of Abraham and every male child in his household. When we understand circumcision's gravity as the mark of belonging to God's people, we grasp why Gershom's uncircumcision in Exodus 4 was not a minor oversight but a violation of the foundational promise that bound Israel together. The covenant carries real consequences because it reflects God's character and His claim upon His people.
The Passover reveals God's precise discrimination: the blood on the doorpost marks a household as God's, and the firstborn within it are spared; unmarked homes face judgment. Zipporah's act in Exodus 4—applying blood to Gershom and calling Moses 'a bridegroom of blood'—echoes this same pattern: blood marks covenant membership and protects from God's judgment. We see that God's sovereignty includes His authority to judge the uncircumcised and to spare the circumcised who bear His sign.
After the golden calf, the Levites alone stood with God and executed His judgment—becoming the priestly tribe through covenant violence. This pattern illuminates Moses himself: his fierce temperament was not a personal flaw but a calling to jealousy for God's covenant. The Zipporah narrative sits within a larger story about covenant enforcement; Moses' very nature was shaped to be an instrument of God's saving and judging work among His people.
Exodus 18 shows Moses overwhelmed by his solitary burden, receiving counsel to delegate and to share the load with others. This follows immediately after the Zipporah narrative, revealing God's intent: Gershom's entry into covenant and Zipporah's role as covenant-keeper signal that Moses was never meant to carry the mission alone. God's plan includes drawing believers into partnership, not as an afterthought, but as the very structure of His redemptive work.
Paul's gratitude for partnership in the gospel mirrors the reality embedded in the Zipporah narrative: we do not serve Christ alone, and our shared labor in His mission is cause for profound joy and thanksgiving. As God brought Zipporah and Gershom into Moses' covenant calling, so Christ draws us into His body, granting us brothers and sisters with whom to labor. This partnership is not a burden to endure but a grace to receive with gladness.
A Prayer for Covenant Belonging and Gospel Partnership
Father, we marvel at your sovereign care over your covenant people. You have not called us to walk alone in your mission, but have graciously assembled us as a body, bringing us into formal membership through the blood of Christ. We confess that we often forget the weight and wonder of covenant—that we are marked as your people, claimed by you, and bound together in a shared calling. We forget that our belonging is not accidental but purposeful, purchased at infinite cost, and meant to equip us for the work you have called us to do together.
In the gospel, we have been brought into covenant through Christ's blood—the true circumcision that marks us as God's own (Colossians 2:11-12). As Zipporah's act formally brought Gershom into the covenant community, so the blood of Jesus has formally brought us into his church. We are no longer strangers or isolated servants, but members of one another, equipped with every grace we need to advance Christ's kingdom.
We ask that you would deepen our gratitude for the gift of partnership in the gospel (Philippians 1:3-4). Give us eyes to see that the brothers and sisters you have placed beside us are not obstacles to our calling but essential to fulfilling it. Grant us courage to encourage one another, wisdom to submit to one another, and joy in the shared labor of making disciples. Help us live as those who understand that we have been assembled for a mission—not called to serve alone, but to serve together as your beloved covenant people.
May we live in the glad reality of our belonging, compelled by grace to love one another fiercely and to advance the gospel together, to your glory and the establishment of your kingdom.
6 questions for your group this week
-
In Exodus 4:24-26, God moves to put someone to death, but the text doesn't explicitly say who the target is. What does the broader narrative context—particularly the firstborn son theme running through Exodus 4:18-31—suggest about whose life was actually in danger, and why does that distinction matter?Exodus 4:22-23, Exodus 4:24-26→ How does understanding that Gershom, not Moses, was threatened change the way you read God's character in this passage?
-
What was the covenant obligation that Gershom had not fulfilled, and what does Zipporah's immediate action—circumcising her son and applying the blood to his feet—tell us about her understanding of what was required to be counted among God's people?Genesis 17, Exodus 4:25
-
The sermon connects Zipporah's act of applying blood to the firstborn to the Passover doorposts in Exodus 12. What is the theological function of blood in both moments, and what does that suggest about how people are marked as belonging to God's covenant community?Exodus 4:25, Exodus 12→ How does recognizing this pattern deepen your understanding of what it means to be 'covered' by the gospel?
-
Moses was called by God to lead Israel into covenant, yet his own firstborn son had been excluded from that covenant. What does this gap between Moses' calling and his family's readiness reveal about a common temptation in gospel work—the notion that we can serve God's mission alone?Exodus 4:18-31→ Where do you see this temptation showing up in your own life or in the culture of our church?
-
The sermon traces how the Levites—a tribe marked by fierce devotion to God's cause—included not only priests like Aaron but warriors who executed God's judgment. How does this fuller picture of what God calls people to do challenge or reshape your sense of what 'ministry' looks like in the body of Christ?Exodus 32:25-29, Genesis 49:5-7
-
If the Zipporah story teaches that God brings people onto his team for his mission—that we are not called to serve alone—how should that truth reshape the way you approach partnerships in the gospel, whether in marriage, in small groups, or in other relationships within the church?Philippians 1:3-4, Exodus 18→ What is one concrete partnership the Lord has given you that you've perhaps been taking for granted, and how might you express gratitude for it this week?
God's Fierce Love for His Team
This prompt helps your family explore what it means to be brought into God's covenant family—and how God uses people we love to keep us from drifting away from Him. Listen for how your kids understand God's protective love, not as rejection, but as fierce care.
In the story, God threatened Moses' son Gershom because he hadn't been marked as one of God's covenant people through circumcision. Zipporah loved her son, so she immediately marked him with blood to bring him into God's family. When has someone you love done something hard or uncomfortable to keep you safe or to make sure you belonged to something important?
Covenant, Partnership, and the Gospel Mission
- The sermon shows how God brought Gershom formally into covenant through Zipporah's faithful act—what does it stir in your heart to consider that God pursues people relationally, not as isolated individuals, and that He calls us into His mission together?
- How does the reality that God designed us for partnership in the gospel—not solitary service—speak to the ways we've been tempted to carry spiritual responsibility alone, or conversely, to isolate from one another in our faith?
- What is one specific way the Lord is calling us, as a couple, to embody this gospel partnership more fully—whether in our marriage, our church community, or our witness—and how can we pray for each other's faithfulness in that?
Exodus 4:24
At a lodging place on the way, the Lord met him and sought to put him to death.
Why this verse: This verse states the critical turning point of the Zipporah narrative—God's covenant threat that sets the entire story in motion. Memorizing it anchors the sermon's central claim that God was enforcing covenant membership through the threat of judgment on the firstborn son, establishing that covenant obedience is not optional but a matter of life and death.
