וְעַמֻּדָ֣יו עֶשְׂרִ֔ים וְאַדְנֵיהֶ֥ם עֶשְׂרִ֖ים נְחֹ֑שֶׁת וָוֵ֧י הָעַמֻּדִ֛ים וַחֲשֻׁקֵיהֶ֖ם כָּֽסֶף׃
As suas colunas serão vinte, e vinte as suas bases, todas de bronze; os colchetes das colunas e as suas faixas serão de prata.
Rashi on Exodus
ועמדיו עשרים AND TWENTY COLUMNS THEREOF — There was a space of five cubits between one column and the other
Rashbam on Exodus
וחשוקיהם מוקפים כסף. The raw material that the bands consisted of matched that of the hooks, i.e. silver.
Tur HaArokh
ועמודיו עשרים, “and its pillars twenty.” The Torah fails to mention the raw material these pillars were made of. Presumably, we are to deduce this by comparing them to other pillars, such as the ones at the entrance to the Sanctuary, and the pillars that supported the dividing curtain. These were all made from acacia wood, expressly stated. (26,32) Also the fact that these pillars were overlaid with silver is not mentioned here, although it is mentioned in Parshat Vayakhel, (36,36)
