Ephesians 5:28-32

So husbands ought also to love their own wives as their own bodies. He who loves his own wife loves himself; for no one ever hated his own flesh, but nourishes and cherishes it, just as Christ also does the church, because we are members of His body. For this reason a man shall leave his father and mother and shall be joined to his wife, and the two shall become one flesh. This mystery is great; but I am speaking with reference to Christ and the church.
