רֵ֘אשִׁ֤ית חָכְמָ֨ה ׀ יִרְאַ֬ת יְהוָ֗ה שֵׂ֣כֶל ט֭וֹב לְכָל־עֹשֵׂיהֶ֑ם תְּ֝הִלָּת֗וֹ עֹמֶ֥דֶת לָעַֽד׃
敬畏永恆者是智慧的開端；凡遵行這些的，都有美好的悟性；他的讚美存到永遠。
Pirkei Avot
Rabbi Hanina ben Dosa said: anyone whose fear of sin precedes his wisdom, his wisdom is enduring, but anyone whose wisdom precedes his fear of sin, his wisdom is not enduring. He [also] used to say: anyone whose deeds exceed his wisdom, his wisdom is enduring, but anyone whose wisdom exceeds his deeds, his wisdom is not enduring.
