256. "And cast dust" (II Shmuel 16:5). HE ASKS, What does it mean, "and cast dust?" AND HE ANSWERS, It was dust by my father, and water by Shim'i, as written, "For it shall be, that on the day you go out, and pass over the wadi of Kidron." It was dust there and water here. Solomon took account of them both so that he will be PUNISHED by dust and water like a Sota (a wife suspected of adultery), he who accused his father by the way.
256. וְעִפָּר בֶּעָפָר מַהוּ. אָמַר שְׁלֹֹמֹה לְגַבֵּי אַבָּא בֶּעָפָר הֲוָה. לְגַבֵּי שִׁמְעִי בְּמַיָּא, דִּכְתִּיב וְהָיָה בְּיוֹם צֵאתְךָ וְעָבַרְתָּ אֶת נַחַל קִדְרוֹן. עָפָר הָתָם, וְהָכָא מַיָּא. תַּרְוַויְיהוּ דָּן שְׁלֹֹמֹה, לְמֶהֱוֵי עָפָר וּמַיָּא כַּסּוֹטָה, לְמַאן דְּאַסְטִין אָרְחָא לְגַבֵּי אֲבוֹי.
