Gen 2:24.   Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh. Matt 19:4-6.   And he answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female, And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh? Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder. Rom 7:3.   So then if, while her husband liveth, she be married to another man, she shall be called an adulteress: but if her husband be dead, she is free from that law; so that she is no adulteress, though she be married to another man. Prov 2:17.   Which forsaketh the guide of her youth, and forgetteth the covenant of her God.
