Ephesians 5:28-31

In the same way, husbands ought to love their wives as they love their own bodies. For a man who loves his wife actually shows love for himself. No one hates his own body but feeds and cares for it, just as Christ cares for the church. And we are members of his body. As the Scriptures say, “A man leaves his father and mother and is joined to his wife, and the two are united into one.”
