'One Flesh' in the Bible

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

and said, 'On account of this a man will leave his father and his mother and will be joined to his wife, and the two will become one flesh'?

So then, they are no longer two but one flesh. Therefore what God has joined together, man must not separate."

and the two will become one flesh,' so that they are no longer two but one flesh.

Or do you not know that the one who joins himself to a prostitute is one body [with her]? For it says, "The two will become one flesh."

Not all flesh [is] the same, but [there is] one flesh of human beings, and another flesh of animals, and another flesh of birds, and another of fish,

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