Matthew 5:28-30

New Catholic Bible

²⁸ But I say to you that anyone who looks with lust at a woman has already committed adultery with her in his heart. ²⁹ If your right eye causes you to sin, tear it out and throw it away. It is preferable for you to lose one part of your body than to have your whole body thrown into Gehenna. ³⁰ And if your right hand causes you to sin, cut it off and throw it away. It is preferable for you to lose one of your limbs than to have your whole body thrown into Gehenna.
