Avot1: 12

הִלֵּל וְשַׁמַּאי קִבְּלוּ מֵהֶם. הִלֵּל אוֹמֵר: הֱוֵי מִתַּלְמִידָיו שֶׁל אַהֲרֹן, אוֹהֵב שָׁלוֹם וְרוֹדֵף שָׁלוֹם, אוֹהֵב אֶת הַבְּרִיּוֹת וּמְקָרְבָן לַתּוֹרָה.

Hillel and Shammai received [the Mesorah] from them. Hillel says: Be from among the students of Aaron, someone who loves peace and pursues peace, who loves people and brings them closer to the Torah.

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].
