Matt.5 Verses 27 to 30

[27] "You have heard that it was said, `You shall not commit adultery.'
[28] But I say to you that every one who looks at a woman lustfully has already committed adultery with her in his heart.
[29] If your right eye causes you to sin, pluck it out and throw it away; it is better that you lose one of your members than that your whole body be thrown into hell.
[30] And if your right hand causes you to sin, cut it off and throw it away; it is better that you lose one of your members than that your whole body go into hell
