כִּ֣י מִֽי־יוֹדֵעַ֩ מַה־טּ֨וֹב לָֽאָדָ֜ם בַּֽחַיִּ֗ים מִסְפַּ֛ר יְמֵי־חַיֵּ֥י הֶבְל֖וֹ וְיַעֲשֵׂ֣ם כַּצֵּ֑ל אֲשֶׁר֙ מִֽי־יַגִּ֣יד לָֽאָדָ֔ם מַה־יִּהְיֶ֥ה אַחֲרָ֖יו תַּ֥חַת הַשָּֽׁמֶשׁ׃
Sebab siapakah yang tahu apa yang baik bagi manusia dalam hidupnya, sepanjang bilangan hari-hari hidupnya yang sia-sia, yang dijalaninya seperti bayang-bayang? Sebab siapakah yang dapat memberitahukan kepada manusia apa yang akan terjadi sesudah dia di bawah matahari?
Rashi
his days are as a fleeting shadow Solomon said (Ecc. 6:12): “that he do them like a shadow,” but he did not explain whether [this refers to] the shadow of a palm or the shadow of a wall, which are permanent. His father already explained, “as a fleeting shadow,” the shadow of a flying bird.
