Matthew 5:28-30

New Revised Standard Version Catholic Edition

²⁸ But I say to you that everyone who looks at a woman with lust 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 better for you to lose one of your members than for your whole body to be thrown into hell.^{[a] 30} And if your right hand causes you to sin, cut it off and throw it away; it is better for you to lose one of your members than for your whole body to go into hell.^[b]
