וְהַכְּלָבִ֣ים עַזֵּי־נֶ֗פֶשׁ לֹ֤א יָֽדְעוּ֙ שָׂבְעָ֔ה וְהֵ֣מָּה רֹעִ֔ים לֹ֥א יָדְע֖וּ הָבִ֑ין כֻּלָּם֙ לְדַרְכָּ֣ם פָּנ֔וּ אִ֥ישׁ לְבִצְע֖וֹ מִקָּצֵֽהוּ׃
Y esos perros ansiosos no conocen hartura; y los mismos pastores no supieron entender: todos ellos miran á sus caminos, cada uno á su provecho, cada uno por su cabo.
Zohar
Woe to the wicked who are shameless and do shameless deeds, for which their children inherit an unclean soul from the unclean side. “Be not like a horse or a mule”, which are lustful above other creatures, for “they which have no understanding” fall a prey to the “dogs which are greedy and can never have enough” (Isa. 56, 11), and which are ready to “shepherd them that have no understanding” (Ibid.) into Gehinnom.
