Mark 10:8

And the two will become one flesh; so that they are no longer two, but one flesh.

Or do you not see that he who is joined to a loose woman is one body with her? for God has said, The two of them will become one flesh.

For this cause will a man go away from his father and his mother and be joined to his wife; and they will be one flesh.

Even so it is right for husbands to have love for their wives as for their bodies. He who has love for his wife has love for himself:
