1 Corinthians 7:2–5

But because of the temptation to sexual immorality, each man should have his own wife and each woman her own husband. The husband should give to his wife her conjugal rights, and likewise the wife to her husband. For the wife does not have authority over her own body, but the husband does. Likewise the husband does not have authority over his own body, but the wife does. Do not deprive one another, except perhaps by agreement for a limited time, that you may devote yourselves to prayer; but then come together again, so that Satan may not tempt you because of your lack of self-control.

Isaiah 62:5

For as a young man marries a young woman,
so shall your sons marry you,
and as the bridegroom rejoices over the bride,
so shall your God rejoice over you.

Genesis 2:23–24

Then the man said, “This at last is bone of my bones
and flesh of my flesh;
she shall be called Woman,
because she was taken out of Man.”
Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh.

Ecclesiastes 4:9–10

Two are better than one, because they have a good reward for their toil. For if they fall, one will lift up his fellow. But woe to him who is alone when he falls and has not another to lift him up!

Hebrews 13:4

Let marriage be held in honor among all, and let the marriage bed be undefiled, for God will judge the sexually immoral and adulterous.

1 Peter 3:7

Likewise, husbands, live with your wives in an understanding way, showing honor to the woman as the weaker vessel, since they are heirs with you of the grace of life, so that your prayers may not be hindered.

Colossians 3:18

Wives, submit to your husbands, as is fitting in the Lord. Husbands, love your wives, and do not be harsh with them.

Matthew 19:4–6

“Have you not read that he who created them from the beginning made them male and female, and said, ‘Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh’? So they are no longer two but one flesh. What therefore God has joined together, let not man separate.”

Genesis 2:18

Then the LORD God said, “It is not good that the man should be alone; I will make him a helper fit for him.”

Ephesians 5:22–27

Wives, submit to your own husbands, as to the Lord. For the husband is the head of the wife even as Christ is the head of the church, his body, and is himself its Savior. Now as the church submits to Christ, so also wives should submit in everything to their husbands. Husbands, love your wives, as Christ loved the church and gave himself up for her, that he might sanctify her, having cleansed her by the washing of water with the word, so that he might present the church to himself in splendor, without spot or wrinkle or any such thing, that she might be holy and without blemish.
