מַה תָּאֳרוֹ. שְׁלֹשָׁה דְבָרִים נֶאֶמְרוּ בָּאוֹב: הַמַּעֲלֶה אוֹתוֹ, רוֹאֵהוּ וְאֵינוֹ שׁוֹמֵעַ קוֹלוֹ, וְהַנִּשְׁאָל לוֹ, שׁוֹמְעוֹ וְאֵינוֹ רוֹאֵהוּ, וּלְפִיכָךְ שָׁאַל מַה תָּאֳרוֹ, וְאַחֵר, לֹא רוֹאֵהוּ וְלֹא שׁוֹמְעוֹ (תנחומא שם): What does he look like. Three things were said regarding אוֹב: The one who conjures him [the dead] up, sees him, but does not hear his voice; the one who inquires of him, hears him, but does not see him, and therefore, he [Shaul] asked, 'What does he look like?', and the others neither see or hear him.
וְהוּא עֹטֶה מְעִיל. שֶׁהָיָה רָגִיל לִלְבֹּשׁ מְעִיל, שֶׁנֶּאֱמַר ״וּמְעִיל קָטֹן תַּעֲשֶׂה לּוֹ אִמּוֹ״ (שמואל א ב:יט), וּבִמְעִילוֹ נִקְבַּר, וְכֵן עָלָה, וְכֵן לֶעָתִיד לָבֹא יַעַמְדוּ בִּלְבוּשֵׁיהֶם (תנחומא שם): He is garbed in a robe. For he was accustomed to wear a robe, as it is stated, "and his mother would make him a small robe."13Above 2:19. He was buried with his robe, and so he arose. And so in the future [Resurrection of the Dead], they will rise with their garments.
