'Two Shall Become One Flesh' in the Bible

and said, 'For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh'?

and the two shall become one flesh.' So they are no longer two, but one flesh.

Or do you not know that he who joins himself to a prostitute becomes one body with her? For, as it is written, "The two shall become one flesh."

"For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh."
