Midrash sobre Proverbios 8:13

Our Rabbis were taught: Three classes of men does the Holy One, praised be He! hate, and they are: He who speaks one way with his mouth, but thinks otherwise in his heart; he who knows testimony [in favor of his neighbor] but does not testify; and he who, having seen his neighbor act indecently, appears as the only witness against him. Like the incident that happened to a certain Tubia, who had sinned, and Zigud appeared as the only witness and testified against him before R. Papa. R. Papa [ordered that] stripes be given Zigud. "What," exclaimed he, "Tubia has sinned, and Zigud should be lashed?" "Yea," replied R. Papa, "since you appear as the only witness against him, it is merely with the intention of creating a bad reputation for him; for it is written (Deu. 19, 15) One witness shall not rise up against a man." R. Nachman b. Isaac said: 'It is, however, meritorious to hate such a man, as it is said (Pr. 8, 13) The fear of the Lord is to hate evil." Our Rabbis were taught: There are three persons whose lives are no lives: The sympathetic, the quick-tempered, and the delicate. "And all could be found in me," remarked R. Joseph. Our Rabbis were taught: Three, love their fellows, and they are: Proselytes, slaves and ravens. Three kinds of creatures hate one another: Dogs, cocks and sorcerers. Some say also harlots, and some add also, the Babylonian scholars.
