Genesis 2:24

1 Corinthians 6:16-17 NIV
Do you not know that he who unites himself with a prostitute is one with her in body? For it is said, “The two will become one flesh.” But whoever is united with the Lord is one with him in spirit.

1 Corinthians 7:2-4 NIV
But since sexual immorality is occurring, each man should have sexual relations with his own wife, and each woman with her own husband. The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. The wife does not have authority over her own body but yields it to her husband. In the same way, the husband does not have authority over his own body but yields it to his wife.

1 Peter 3:1-7 NIV
Wives, in the same way submit yourselves to your own husbands so that, if any of them do not believe the word, they may be won over without words by the behavior of their wives, when they see the purity and reverence of your lives. Your beauty should not come from outward adornment, such as elaborate hairstyles and the wearing of gold jewelry or fine clothes. Rather, it should be that of your inner self, the unfading beauty of a gentle and quiet spirit, which is of great worth in God’s sight. For this is the way the holy women of the past who put their hope in God used to adorn themselves. They submitted themselves to their own husbands, like Sarah, who obeyed Abraham and called him her lord. You are her daughters if you do what is right and do not give way to fear. Husbands, 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.

Ephesians 5:28-31 NIV
In this same way, husbands ought to love their wives as their own bodies. He who loves his wife loves himself. After all, no one ever hated their own body, but they feed and care for their body, just as Christ does the church— for we are members of his body. “For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh.”

Matthew 19:3-9 NIV
Some Pharisees came to him to test him. They asked, “Is it lawful for a man to divorce his wife for any and every reason?” “Haven’t you read,” he replied, “that at the beginning the Creator ‘made them male and female,’ and said, ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh’ ? So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.” “Why then,” they asked, “did Moses command that a man give his wife a certificate of divorce and send her away?” Jesus replied, “Moses permitted you to divorce your wives because your hearts were hard. But it was not this way from the beginning. I tell you that anyone who divorces his wife, except for sexual immorality, and marries another woman commits adultery.”

Proverbs 31:10 NIV
A wife of noble character who can find? She is worth far more than rubies.

Romans 7:2 NIV
For example, by law a married woman is bound to her husband as long as he is alive, but if her husband dies, she is released from the law that binds her to him.
