Мусар к Йешайау 51:18

אֵין־מְנַהֵ֣ל לָ֔הּ מִכָּל־בָּנִ֖ים יָלָ֑דָה וְאֵ֤ין מַחֲזִיק֙ בְּיָדָ֔הּ מִכָּל־בָּנִ֖ים גִּדֵּֽלָה׃

Нет никого, кто бы мог вести ее среди всех сыновей, которых она родила; И нет никого, кто бы взял ее за руку от всех сыновей, которых она воспитала.

And the prophet further said: "She has none to guide her out of all the sons she bore, none takes her hand of all the sons she raised" (Yeshaya 51:18). And "all flesh is grass, and all his kindness is as the blossom of the field" (Isaiah 40:6), which our sages of blessed memory, explained: "all the kindness they do is only for themselves" (Zohar Chadash 117a, Tikunei Zohar 30,63a), i.e. for their own good and benefit; they do not intend for this perfect intention and do not seek the raising of G-d's honor and the redemption of Israel.
