Rashi on Exodus 38:27/רש"י על שמות ל״ח:כ״ז

1לצקת means as the Targum has it: לאתכא, TO CAST.

2את אדני הקדש THE SOCKETS OF THE SANCTUARY — i. e. of the boards of the Tabernacle (the Sanctuary) which were forty-eight boards, and for these ninety-six sockets were required. The sockets for the partition vail were four in number, so we have altogether one hundred. As regards all the other sockets (those of the enclosure and of the vail at its entrance) they are not taken into account here, because “copper” was written concerning them (Scripture prescribes that they were to be of copper).
