Avot1: 13
הוּא הָיָה אוֹמֵר: נְגַד שְׁמָא — אֲבַד שְׁמֵהּ. וּדְלָא מוֹסִיף — יָסֵיף. וּדְלָא יָלִיף — קְטָלָא חַיָּב. וּדְאִשְׁתַּמֵּשׁ בְּתַגָּא — חֳלָף.
He used to say: [If] one becomes renowned, he will [eventually] lose his renown. And he who does not increase will decrease. And one who did not learn is liable to death. And one who makes use of the crown will pass [away].
