5. Further it reads, " ...Who knows not how to take care of himself." It is not written, 'To take care of others,' but, "to take care of himself." Why? Because it is foolish. In this regard, Solomon said, "And the fool walks in darkness" (Kohelet 2:14), because this foolishness comes from the refuse of darkness and will never have light. BUT HE WHO DOES NOT KNOW HOW TO TAKE CARE OF OTHERS IS NOT YET CONSIDERED FOOLISH.
5. אֲשֶׁר לֹא יָדַע לְהִזָּהֵר עוֹד, לְהַזְהִיר לָא כְתִיב, אֶלָּא לְהִזָּהֵר, בְּגִין דְּאִיהוּ כְסִיל, וַעֲלֵיהּ אֲמַר שְׁלֹמֹה ע"ה, וְהַכְּסִיל בַּחֹשֶׁךְ הוֹלֵךְ, דְּהָא מֵסּוּסִיתָא דְּחֹשֶׁךְ קָא אַתְיָא, וְלֵית לֵיהּ נְהוֹרָא לְעָלְמִין.
