The tents of the Imahos (matriarchs) had three constants which parallel the three mitzvos of women. Their neiros (candles) were lit from Erev Shabbos to Erev Shabbos, their Challos stayed fresh from week to week, and there was a cloud above the tent signifying Hashem's presence. The candles represent the mitzva of lighting Shabbos candles, the Challos represent the mitzva of Hafrashas Challah (separating the Challah) and the cloud represents the mitzvos of Tarahas Hamishpacha (family purity). In our parsha we see a further connection to the keilim (vessels) of the Beis Hamikdash. Lighting the candles corresponds to the Menorah, the Challos correspond to the Challah on the Shulchan, and the laws of Taharas Hamishpacha correspond to the Ketores.
