וְיֹתֵ֥ר מֵהֵ֖מָּה בְּנִ֣י הִזָּהֵ֑ר עֲשׂ֨וֹת סְפָרִ֤ים הַרְבֵּה֙ אֵ֣ין קֵ֔ץ וְלַ֥הַג הַרְבֵּ֖ה יְגִעַ֥ת בָּשָֽׂר׃
내 아들아 또 경계를 받으라 여러 책을 짓는 것은 끝이 없고 많이 공부하는 것은 몸을 피곤케 하느니라
Ecclesiastes
Koheleth sought to find [and found] things of desire [("laws to Moses on Sinai") and righteous writ [(the Written Torah and the Prophets)].
Proverbs
What [did you do that make people call you (pejoratively)] my son [and not the son of your father (an acknowledged tzaddik)]? And what [did you do], the son of my womb? [i.e., the son whom I nurtured in my womb (with additional intercourse, so that he be "whitened and quickened")] And what [did you do], the son of my vows [(whom I vowed would be "whitened" in Torah)]?
