וְהַכֹּהֵן֩ הַגָּד֨וֹל מֵאֶחָ֜יו אֲֽשֶׁר־יוּצַ֥ק עַל־רֹאשׁ֣וֹ ׀ שֶׁ֤מֶן הַמִּשְׁחָה֙ וּמִלֵּ֣א אֶת־יָד֔וֹ לִלְבֹּ֖שׁ אֶת־הַבְּגָדִ֑ים אֶת־רֹאשׁוֹ֙ לֹ֣א יִפְרָ֔ע וּבְגָדָ֖יו לֹ֥א יִפְרֹֽם׃
Aquele que é sumo sacerdote entre seus irmãos, sobre cuja cabeça foi derramado o óleo da unção, e que foi consagrado para vestir as vestes sagradas, não descobrirá a cabeça nem rasgará a sua vestidura;
Pirkei Avot
Rabbi Ishmael his son said: He who learns in order to teach, it is granted to him to study and to teach; But he who learns in order to practice, it is granted to him to learn and to teach and to practice. Rabbi Zadok said: do not make them a crown for self-exaltation, nor a spade with which to dig. So too Hillel used to say, “And he that puts the crown to his own use shall perish.” Thus you have learned, anyone who derives worldly benefit from the words of the Torah, removes his life from the world.
