Matthew 5:27-29 Common English Bible (CEB)
Law of adultery
27 “You have heard that it was said, Don’t commit adultery.[a] 28 But I say to you that every man who looks at a woman lustfully has already committed adultery in his heart. 29 And if your right eye causes you to fall into sin, tear it out and throw it away. It’s better that you lose a part of your body than that your whole body be thrown into hell.
