ציטירנדיקער פּירוש אויף דברי הימים א 11:1

We find these thoughts expressed clearly in the Sefer Habahir (item 121-122), (the question being what is meant in Psalms 146,10 ימלוך ה' אלו-היך ציון לדור ודור), whereas in Chronicles I 11,1 Zion is described as ציון עיר דוד, as if the city belongs exclusively to David (who lived only for one generation). Rabbi Akiva said that when Kohelet writes: דור הולך ודור בא, the meaning is [not the generally accepted one that a generation appears on the stage of history only to be replaced by the next generation, Ed.] “a generation follows a generation which has already left the stage of history, i.e. “it reappears on the stage of history.” We can describe this in terms of a parable of a king who had many servants and who outfitted them in all kinds of exotic uniforms in accordance with his means. When the servants were found soiling their uniforms the king stripped them of these fancy uniforms and dismissed them. The king then laundered all these uniforms carefully until no trace of their stains and dirt remained. He hung them up for storage; in the meantime the king acquired other servants whom he provided with the uniforms previously worn by the first set of servants who had not displayed much care about their outfits. At that time the king did not yet know if the new servants would prove worthier of their uniforms than the ones he had dismissed. Nonetheless, these new servants were recipients of uniforms which had been worn before them. Thus far the comment in the Sefer Habahir.
