אָכְל֤וּ זָרִים֙ כֹּח֔וֹ וְה֖וּא לֹ֣א יָדָ֑ע גַּם־שֵׂיבָה֙ זָ֣רְקָה בּ֔וֹ וְה֖וּא לֹ֥א יָדָֽע׃
פֿרעמדע האָבן אױפֿגעגעסן זײַן כּוֹח, און ער מערקט ניט; שױן גראָע האָר דורכגעשפּריצט בײַ אים, און ער מערקט ניט.
Duties of the Heart
It was already said that the days are like scrolls, write on them what you would like to be remembered by, and the verse says: "Be you not as the horse, or as the mule, which have no understanding" (Tehilim 32:9), and it is said of one who prolonged his time of ignoring to make a personal accounting "also old age was cast into him, but he did not know" (Hoshea 7:9).
