חסידות אויף איוב 38:13

Because regarding the future time to come it says, (Job 38:13) "To grab the wings of the earth and shake the wicked from it." That He [Hashem] will hold on to the ends of the earth and shake the evildoers [from it], but whoever is close to the True Tzaddik he will grab on to and hold himself with the Tzaddik and he will remain standing, and won't be shaken with the wicked since he is grabbing on to and holding on to the Tzaddik.
