וְעַמֻּדָ֣יו עֶשְׂרִ֔ים וְאַדְנֵיהֶ֥ם עֶשְׂרִ֖ים נְחֹ֑שֶׁת וָוֵ֧י הָעַמֻּדִ֛ים וַחֲשֻׁקֵיהֶ֖ם כָּֽסֶף׃
그 기둥이 스물이며 그 받침 스물은 놋으로 하고 그 기둥의 갈고리와 가름대는 은으로 할찌며
The Third Beit HaMikdash
The verse uses the word ְחִשֻּׁקֵיהֶם to refer to the wheels’ rims. The rims connect the spokes, which are referred to as חִשֻּׁרֵיהֶם. The term חִשֻּׁקֵיהֶם is also used when the Torah discusses the Mishkan:8See Shmos 27:10. “Their bands (חִשֻּׁקֵיהֶם) were silver.” The rim of a wheel is the part of the wheel that revolves and is in contact with the earth. Usually, wheels have an iron rim. Thus, the mishnah9Keilim 11:3. mentions “an iron rim.” In this instance, it was not necessary for the wheels to have an iron rim, because the wheel was made entirely of copper.10Copper is both ductile and tough, making it easy to shape into wheels and sturdy enough not to need an outer iron rim.
