Matthew 5:27-29

27“You have heard that it was said, ‘You shall not commit adultery.’

28But I tell you that everyone who looks upon a woman to lust after her has already committed adultery with her in his heart.

29And if your right eye causes you to stumble, gouge it out and throw it away! It is better for you that one part of your body should be destroyed, than that your whole body be thrown into Gehenna.
