בְּהַשְׁאָלָה: סִלֵּק אוֹתוֹ. הֵצֵר אֶת צְעָדָיו. הִסִּיג אֶת גְּבוּלוֹ. הִתְחָרָה בּוֹ וְקִלְקֵל אֶת עֲסָקָיו.
("הַמְּהַלֵּךְ בְּקוֹמָה זְקוּפָה...כְּאִלּוּ דּוֹחֵק רַגְלֵי שְׁכִינָה"- בְּרָכוֹת מג ע"ב, וְכֵן:"שֶׁכָּל אָדָם חוֹשֵׁשׁ מִשּׁוּם חֲבֵרוֹ שֶׁהוֹלֵךְ עִמּוֹ, שֶׁאִם תָּבוֹא יְשׁוּעָה לֹא יִדְחֹק חֲבֵרוֹ אֶת רַגְלָיו"-עַגְנוֹן/ עִיר וּמְלוֹאָהּ, 675)
