The Master is Urgent

רַבִּי טַרְפוֹן אוֹמֵר הַיּוֹם קָצֵר וְהַמְּלָאכָה מְרֻבָּה והַפּוֹעֲלִים עֲצֵלִים וְהשָּׂכָר הַרְבֵּה וּבַעַל הַבַּיִת דּוֹחֵק

פרקי אבות

"Rabbi Tarfon said, The day is short, and the work is great, and the labourers are sluggish, and the reward is greatm and the Master is urgent."

-Sayings of the Fathers 2.20 (Translated by Rabbi JH Hertz)
