Matthew 5:
31 "It has been said, 'Anyone who divorces his wife must give her a certificate of divorce.'
32 But I tell you that anyone who divorces his wife, except for sexual immorality, makes her the victim of adultery, and anyone who marries a divorced woman commits adultery.
John 15:13
Greater love has no one than this: to lay down one's life for one's friends.
Ephesians 5:28
In this same way, husbands ought to love their wives as their own bodies. He who loves his wife loves himself.
Mark 10:
5 "It was because your hearts were hard that Moses wrote you this law," Jesus replied.
6 "But at the beginning of creation God 'made them male and female.'
7 'For this reason a man will leave his father and mother and be united to his wife,
8 and the two will become one flesh.' So they are no longer two, but one flesh.
9 Therefore what God has joined together, let no one separate."
