אאַל תְּבַהֵל בְּרוּחֲךָ לִכְעוֹס, אָמַר רַבִּי יוּדָן הֵכְמָה דְּמַעֲזֵילָא עָזֵיל עַל פְּלַכְתֵּיהּ כֵּן סָלֵיק לֵיהּ בִּפְלַכְתֵּיהּ הוּא נָסֵיב, הֵיךְ מַה דְּקִימְקוּמָא גָּלֵישׁ עַל גִּיסֵיהּ שָׁפֵיךְ כָּל דְּרָקַק לְעֵיל עַל אַפּוֹי נְפַל.
1“Do not be hasty in your spirit, to become angry, as anger rests in the bosom of fools” (Ecclesiastes 7:9).“Do not be hasty in your spirit, to become angry.” Rabbi Yudan said: As the spinner spins [thread] on his spindle, so it comes to him; from his spindle, he takes.70 When the kettle overflows, it spills on him. When one spits upward, it falls on his face.71
