וְעָשִׂ֥יתָ שֻׁלְחָ֖ן עֲצֵ֣י שִׁטִּ֑ים אַמָּתַ֤יִם אָרְכּוֹ֙ וְאַמָּ֣ה רָחְבּ֔וֹ וְאַמָּ֥ה וָחֵ֖צִי קֹמָתֽוֹ׃
און זאָלסט מאַכן אַ טיש פֿון שִטים-האָלץ; צװײ אײלן זײַן לענג, און אַן אײל זײַן ברײט, און אַן אײל און אַ האַלב זײַן הײך.
Rashi
קמתו THE HEIGHT THEREOF — i. e. the height of its legs together with the thickness of the table-board.
Alshekh
Make a ledge. The table signifies wealth while the ledge around it indicates that a person must take measures to see that his wealth is not lost. The way to do this is by giving generously to charity. Thus the four legs supporting the table signify the poor, the proselyte, the orphan and the widow (Alsheich).
Chizkuni
ועשית שלחן, “you are to construct a table;” it is no more than elementary courtesy that the king’s servants and members of his household should eat at his table.
