For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh. (NIV)

Therefore a man shall leave his father and his mother and shall become united and cleave to his wife, and they shall become one flesh. [Matt. 19:5; I Cor. 6:16; Eph. 5:31-33.] (AMP)

Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh. (KJV)
