חוֹלֵ֣ק עִם־גַּ֭נָּב שׂוֹנֵ֣א נַפְשׁ֑וֹ אָלָ֥ה יִ֝שְׁמַ֗ע וְלֹ֣א יַגִּֽיד׃
O que é sócio do ladrão odeia a sua própria alma; sendo ajuramentado, nada denuncia.
Rashi on Proverbs
he hears an oath that they adjure him, “Did you see so and so who stole so much and so much from me?” And since he shares with him, he does not testify.
