Matthew 5:27-32

27Ye have heard that it has been said, Thou shalt not commit adultery.

28But I say unto you, that every one who looks upon a woman to lust after her has already committed adultery with her in his heart.

29But if thy right eye be a snare to thee, pluck it out and cast it from thee: for it is profitable for thee that one of thy members perish, and not thy whole body be cast into hell.

30And if thy right hand be a snare to thee, cut it off and cast it from thee: for it is profitable for thee that one of thy members perish, and not thy whole body be cast into hell.

31It has been said too, Whosoever shall put away his wife, let him give her a letter of divorce.

32But I say unto you, that whosoever shall put away his wife, except for cause of fornication, makes her commit adultery, and whosoever marries one that is put away commits adultery.
