Matthew 18:8-9

8If your hand or your foot causes you to do wrong things, you should cut it off. You should throw it away. It is better to have only one hand or one foot and to have God's true life. It will be much worse to keep both your hands and both your feet and still do wrong things. Then God will throw you into hell, where the fire always burns.

9If your eye causes you to do wrong things, then you should take it out. You should throw it away. It is better to have only one of your eyes and to have God's true life. It will be much worse if you keep both your eyes but then God throws you into hell. There the fire always burns.
