LOOK INTO THE MIRROR FIRST
The verse states “Do not hate your brother in your heart, rather, you should reprimand him and do not carry on him any wrongdoing.” The Talmud teaches us that although we may hate one who fails to accept the Torah, nevertheless, we must not hold that hatred in the heart. We must reprimand him.
What is the intent of “do not carry on him any wrongdoing”? Rebbe Tarfon says (Erchichin 16b) “I wonder if there is anyone nowadays who can give a successful ‘tochacha’.” He explains, this is because if the one giving the tochacha tells the wrongdoer that he is doing wrong, the recipient will turn around and tell the reprimander that he is doing greater wrong in the same area or in some other area. The recipient will therefore pay no attention to the words of the reprimander.
