Mark 10:8

Modern King James Version

And the two of them shall be one flesh. So then they are no longer two, but one flesh.

See the chapter Copy

So men ought to love their wives as their own bodies. He who loves his wife loves himself.

Therefore shall a man leave his father and his mother, and shall cleave to his wife and they shall be one flesh.

Or do you not know that he being joined to a harlot is one body? For He says, The two shall be one flesh.

Therefore what God has joined together, let not man put apart.
