Numbers 4:32

ויתדתם ומיתריהם [AND THE COLUMNS OF THE ENCLOSURE ROUND ABOUT IT AND THEIR SOCKETS] AND THEIR PINS, AND THEIR CORDS — i.e. the pins and cords of the columns only, because the pins and cords of the hangings were part of the burden of the Gershonites (not of the sons of Merari). There were, as a matter of fact, pegs and cords for the curtains and the hangings on their lower edges in order that the wind should not raise them, there were also pegs and cords for the columns, round about, upon which to suspend the hangings by their upper edges on poles and rails, just as it is set forth in the Boraitha dealing with the work of the Tabernacle (cf. Rashi on Exodus 27:10, 19; Numbers 3:26 and our Note thereon).

וְעַמּוּדֵי֩ הֶחָצֵ֨ר סָבִ֜יב וְאַדְנֵיהֶ֗ם וִיתֵֽדֹתָם֙ וּמֵ֣יתְרֵיהֶ֔ם לְכׇ֨ל־כְּלֵיהֶ֔ם וּלְכֹ֖ל עֲבֹדָתָ֑ם וּבְשֵׁמֹ֣ת תִּפְקְד֔וּ אֶת־כְּלֵ֖י מִשְׁמֶ֥רֶת מַשָּׂאָֽם׃

and the pillars of the court round about, and their sockets, and their pegs, and their cords, with all their instruments, and with all their service: and by name you shall reckon the instruments of the charge of their burden.
