Mark 10:8

Weymouth NT

and the two shall be one'; so that they are two no longer, but `one.'

See the chapter Copy

What, therefore, God has joined together let not man separate.«

Or do you not know that a man who has to do with a prostitute is one with her in body? For God says, »The two shall become one.«

So too married men ought to love their wives as much as they love themselves. He who loves his wife loves himself.
