Genesis 2:24
24That is why a man leaves his father and mother and is united to his wife, and they become one flesh.
Jesus and Paul both return to this verse. Leaving and joining form a new household, described as becoming one flesh.
Bible Verses About Marriage
Scripture describes marriage as a covenant that makes two people one household. Its instructions give responsibilities to both spouses. Ephesians 5 begins with mutual submission, then devotes about three times as many words to the responsibility of husbands. Read from the beginning, the passage centers self-giving love.
Marriage is a covenant that forms a new household
The foundational passages speak of leaving, joining, and becoming one. Their language describes a durable bond with public significance.
Mark 10:9
9Therefore what God has joined together, let no one separate.”
Jesus cites Genesis when asked about divorce, in a conversation where his answer protects the spouse made vulnerable by casual divorce.
Hebrews 13:4
4Marriage should be honored by all, and the marriage bed kept pure, for God will judge the adulterer and all the sexually immoral.
Everyone is told to honor marriage, giving the covenant a public as well as private dimension.
The obligations run in both directions
Reading the household passages from their opening changes their emphasis. They begin with a mutual instruction and give husbands the longer, costlier assignment.
Ephesians 5:21
21Submit to one another out of reverence for Christ.
This sentence calls the whole church to submit to one another and introduces the household instructions that follow.
Ephesians 5:25
25Husbands, love your wives, just as Christ loved the church and gave himself up for her
Husbands are given Christ's self-giving for the church as the standard for their love.
Colossians 3:19
19Husbands, love your wives and do not be harsh with them.
Paul's shorter instruction explicitly prohibits husbands from being harsh with their wives.
1 Peter 3:7
7Husbands, in the same way be considerate as you live with your wives, and treat them with respect as the weaker partner and as heirs with you of the gracious gift of life, so that nothing will hinder your prayers.
Peter ties considerate treatment of a wife to a husband's prayers being hindered, giving mistreatment a direct spiritual consequence.
The practical case is companionship
Alongside the covenant language, Scripture is plain that the ordinary good of marriage includes companionship and practical support.
Genesis 2:18
18The Lord God said, “It is not good for the man to be alone. I will make a helper suitable for him.”
A person's solitude is the first thing Genesis calls "not good." This establishes companionship as a basic human good.
Ecclesiastes 4:9-12
9Two are better than one,
because they have a good return for their labor:
10If either of them falls down,
one can help the other up.
But pity anyone who falls
and has no one to help them up.
11Also, if two lie down together, they will keep warm.
But how can one keep warm alone?
12Though one may be overpowered,
two can defend themselves.
A cord of three strands is not quickly broken.
Though it isn't specifically about marriage, this passage is often read at weddings. Two people can work, recover, and endure together.
Limits and common misreadings
Ephesians 5 is the most misused passage in this collection. It is routinely quoted as "wives, submit", skipping verse 21's instruction to "submit to one another," and stopping before the far longer and costlier command to husbands. That fragment can become a warrant for control even though the passage sets self-sacrifice as its standard. More seriously, these verses are used to keep people in abusive marriages. Nothing in Scripture requires anyone to remain in danger; Peter explicitly ties a husband's mistreatment of his wife to his prayers being hindered, and the prophets treat covenant-breaking as the offense of the one who breaks it. If you are being harmed, these passages are not an instruction to stay.
The opening of Ephesians 5:21 matters for everything that follows. Paul first tells the church to submit to one another out of reverence for Christ, then addresses wives and husbands within that shared frame.
His longer instruction to husbands measures love by Christ giving himself for the church. The passage therefore places power under the demands of mutual care and self-giving love.
Common questions about marriage
What does Ephesians 5 say about marriage?
It opens in verse 21 by telling the whole church to submit to one another out of reverence for Christ, then addresses wives briefly and husbands at roughly three times the length. The standard set for husbands is Christ giving himself up for the church. Quoting only from verse 22 leaves out the mutual frame and the longest instruction.
What does "the two shall become one flesh" mean?
Genesis 2:24 describes a new household formed by leaving one's parents and being joined to a spouse. "One flesh" names a union that is physical, economic, and social. Jesus cites it in Mark 10 to argue that marriage is not casually dissolved, and Paul uses it in Ephesians as a picture of Christ and the church.
