לֹֽא־תִשְׂנָ֥א אֶת־אָחִ֖יךָ בִּלְבָבֶ֑ךָ הוֹכֵ֤חַ תּוֹכִ֙יחַ֙ אֶת־עֲמִיתֶ֔ךָ וְלֹא־תִשָּׂ֥א עָלָ֖יו חֵֽטְא׃
너는 네 형제를 마음으로 미워하지 말며 이웃을 인하여 죄를 당치 않도록 그를 반드시 책선하라
Sha'arei Kedusha
Our sages, of blessed memory, related436Talmud Bavli, Yoma 9b that during the period of the second Holy Temple, there were many righteous Tzaddikim and Torah Scholars. Nonetheless, the Holy Temple was destroyed only because of the sin of baseless hatred. They likewise said that the exile was lengthened and its end was concealed solely due to baseless hatred. Furthermore, in regard to all other sins, a person is only in a state of transgression when he actively violates them, whereas baseless hatred is a constant transgression that one carries in his heart. Therefore, he is in violation of the negative mitzvah,437Leviticus 19:17 “You shall not hate your brother in your heart” and negates the positive mitzvah of,438Leviticus 19:18 “You shall love your fellow as yourself,” at every moment.
