Parshas Emor

In Parshas Emor we find a few posukim that talk about the Lechem Haponim that were set on the Shulchan. The Posuk (24;8) says “Beyom hashabbos beyom hashabbos yarchenu lefnai Hashem” loosely translated - Each Shabbos he shall set it before Hashem. What has to be understood is why does the Torah repeat the words “beyom hashabbos”? The Alshich explains this by pointing out that the Lechem Haponim were actually on the Shulchan for eight days. The day they were put on- Shabbos, is day one and taken off the following Shabbos which is day eight- the point of it being eight days is of great significance, but we’ll leave that for now. That is what the meaning behind the writing two times “beyom hashabbos”.
Chazal say (Shabbos 118) that if Klal Yisroel would keep two Shabbosim they would be redeemed. The Sedurai Shel Shabbos in his hakdomah explains that Shabbos lasts until the following Tuesday. The new Shabbos comes in on the Wednesday before. (Hence we end off the Shiur of Wednesday with the first posak of lecha nerannenah). He says that if we really kept Shabbos it would take us through the week up until the next Shabbos. The Gemorah is telling us that is we keep two Shabbosim- meaning we connect the two Shabbosim. If Shabbos lasts us till Tuesday and we are ready for Shabbos Wednesday then our whole week is one big Shabbos and that is what can bring the Geulah. May we suggest that this is the lesson of the Lechem Haponim. It rested in the Mishkan from Shabbos to Shabbos for Eight days thus connecting the two Shabbosim- making it one day “shekoolo Shabbos”.
