'One Flesh' in the Bible

Therefore a man will leave his father and his mother, and will join with his wife, and they will be one flesh.

and said, 'For this cause a man shall leave his father and mother, and shall join to his wife; and the two shall become one flesh?'

So that they are no more two, but one flesh. What therefore God has joined together, do not let man tear apart."

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

Or do you not know that he who is joined to a prostitute is one body? For, "The two," says he, "will become one flesh."

All flesh is not the same flesh, but there is one flesh of men, another flesh of animals, another of fish, and another of birds.

"For this cause a man will leave his father and mother, and will be joined to his wife. The two will become one flesh."
