Matthew 5:28-39

28but I say to you that everyone who [so much as] looks at a woman with lust for her has already committed adultery with her in his heart.

29If your right eye makes you stumble and leads you to sin, tear it out and throw it away [that is, remove yourself from the source of temptation]; for it is better for you to lose one of the parts of your body, than for your whole body to be thrown into hell.

30If your right hand makes you stumble and leads you to sin, cut it off and throw it away [that is, remove yourself from the source of temptation]; for it is better for you to lose one of the parts of your body than for your whole body to go into hell.

31“It has also been said, ‘Whoever divorces his wife is to give her a certificate of divorce’;

32but I say to you that whoever divorces his wife, except on grounds of sexual immorality, causes her to commit adultery; and whoever marries a woman who has been divorced commits adultery.

33“Again, you have heard that it was said to the men of old, ‘You shall not make false vows, but you shall fulfill your vows to the Lord [as a religious duty].’

34But I say to you, do not make an oath at all, either by heaven, for it is the throne of God;

35or by the earth, for it is the footstool of His feet; or by Jerusalem, for it is the city of the Great King.

36Nor shall you make an oath by your head, for you are not able to make a single hair white or black.

37But let your statement be, ‘Yes, yes’ or ‘No, no’ [a firm yes or no]; anything more than that comes from the evil one.

38“You have heard that it was said, ‘An eye for an eye, and a tooth for a tooth [punishment that fits the offense].’

39But I say to you, do not resist an evil person [who insults you or violates your rights]; but whoever slaps you on the right cheek, turn the other toward him also [simply ignore insignificant insults or trivial losses and do not bother to retaliate—maintain your dignity, your self-respect, your poise].
