ה֣וֹן עָ֭שִׁיר קִרְיַ֣ת עֻזּ֑וֹ וּכְחוֹמָ֥ה נִ֝שְׂגָּבָ֗ה בְּמַשְׂכִּיתֽוֹ׃
Богатый человек'Его богатство - его сильный город, И как высокая стена в его собственном тщеславии.
Rashi on Proverbs
and like a strong wall his wealth is to him in his chambers. Since the house is paved with a floor of stones that cover the earth, it is called אבן משכית, a covering stone.
