לְהַעֲלֹת נֵר תָּמִיד ...to kindle the candle continually [Shemos 27:28]
Regarding the Menorah, the Torah says, “...the seven candles should radiate the light.” [Bamidbar 8:2] What is the light that Torah is referring to? The Nesivos Shalom explains that it is the Ohr HaGanuz — the magnificent light that was created on the first day of creation and then hidden away.
The Nesivos Shalom further writes, that even nowadays we benefit from the light of the Menorah - Shabbos Kodesh is what radiates that light! In fact, the Baal HaTurim points out that the words נר תמיד have the same gematria as בשבת (on Shabbos). This is another indication says the Nesivos Shalom that even without the presence of the Beis HaMikdash, the light of the Menorah is תמיד (continual), because it radiates on Shabbos.
The Nesivos Shalom further teaches that the seven candles of the Menorah correspond to the seven days of the weeks, because the light of Shabbos shines upon all seven days of the week.
Knowing this, we should cherish that beautiful light of Shabbos and look forward to it each day.
