You shall not commit adultery (Exodus 20.14)

The Lord God said: "It is not good for the man to be alone. I will make a suitable partner for him."
(Genesis 2:18)

That is why a man leaves his father and mother and clings to his wife, and the two of them become one body.
(Genesis 2:24)

But from the beginning of creation, 'God made them male and female. For this reason a man shall leave his father and mother (and be joined to his wife), and the two shall become one flesh.' So they are no longer two but one flesh. Therefore what God has joined together, no human being must separate."
(Mark 10:6-10)

Each one of you should love his wife as himself, and the wife should respect her husband.
(Ephesians 5:33)

The husband should fulfill his duty toward his wife, and likewise the wife toward her husband. A wife does not have authority over her own body, but rather her husband, and similarly a husband does not have authority over his own body, but rather his wife.
(1 Corinthians 7:3-4)

Be subordinate to one another out of reverence for Christ. Wives should be subordinate to their husbands as to the Lordů Husbands, love your wives, even as Christ loved the church and handed himself over for her.
(Ephesians 5:21-22,25)

"You have heard that it was said, 'You shall not commit adultery.' But I say to you, everyone who looks at a woman with lust has already committed adultery with her in his heart."
(Matthew 5.27-28)

"I say to you, whoever divorces his wife (unless the marriage is unlawful) and marries another commits adultery."
(Matthew 19.9)

Some are incapable of marriage because they were born so; some, because they were made so by others; some, because they have renounced marriage for the sake of the kingdom of heaven. Whoever can accept this ought to accept it."
(Matthew 19:12)

At the resurrection they neither marry nor are given in marriage but are like the angels in heaven.
(Matthew 22:30)

Let marriage be honored among all
(Hebrews 13:4)
