Mattityahu 5:27-29

Orthodox Jewish Bible

²⁷ You have heard that it was said, LO TINAF (Do not commit adultery, SHEMOT 20:14).

²⁸ But I say to you that everyone looking upon a woman with taavah (lust) for her has already committed niuf (adultery) with her in his heart.

²⁹ And if your right eye causes you to commit chet (sin), tear it out and throw it from you, for it is better for you that one of your evarim (members) be lost and not your whole basar (body, flesh) be thrown into Gehinnom.
