“Why is the mitzva to make a Kiyor for the Mishkan in this week’s parsha, and not in parshas Teruma together with all the other Keilim?”
if you look at the first shtikel of meshech chochma on parshas ki sisa, although he doesn’t ask yur kashah, he neverthless answers it beautifully.
[washing the hands and feet aren’t a din in the kiyor per se, but in the makom (i.e. between the mizbayach and ohel moed.) ???? ??]
