'One Flesh' in the Bible

For this cause shall a man leave father and mother and cleave unto his wife, and they shall be one flesh.

and said, 'For this thing, shall a man leave father and mother, and cleave unto his wife, and they twain shall be one flesh.'

Wherefore now are they not twain, but one flesh. Let not man therefore put asunder, that which God hath coupled together."

and they twain shall be made one flesh.' So then are they now not twain, but one flesh.

Do ye not understand that he which coupleth himself with a harlot, is become one body? "For two," saith he, "shall be one flesh."

"For this cause shall a man leave father and mother, and shall continue with his wife, and two shall be made one flesh."
