Matthew 5:27-30
27 “You have heard that it was said, Do not commit adultery. 28 But I tell you, everyone who looks at a woman to lust for her has already committed adultery with her in his heart. 29 If your right eye causes you to sin, gouge it out and throw it away. For it is better that you lose one of the parts of your body than for your whole body to be thrown into hell. 30 And if your right hand causes you to sin, cut it off and throw it away. For it is better that you lose one of the parts of your body than for your whole body to go into hell!
