פירוש על מגילה 32:18

Initially in the days of Cyrus, when Zerubavel went up (with him) from exile, Mordekhai was with him, and they were listed in the book of Ezra. There were twenty-four years between [the first] listing and the listing of the later Cyrus. And because Modekhai was made into a minister in between, he went down in his importance for the Sages.
