Musar su Isaia 60:2

G–d has granted me the insight to find the answer to this problem with the help of a Midrash Tanchuma on our verse. It is customary in civilised countries that when a king places a divan and table in his room that he places the candlestick to the left of the table. In the Holy Temple, however, this was not so. The Candlestick was placed on the right side of the Table to make it plain that G–d is not in need of any light supplied by us. The purpose of the Candlestick is to light the way for you to the World to Come at the time when darkness will sweep the Gentiles, for we know from Isaiah 60,2 that at that time החשך יכסה ארץ וערפל לאומים ועליך יזרח ה' וכבודו עליך יראה, "The darkness will envelop the earth, and thick clouds the nations; but upon you the Lord will shine and His Presence will be seen over you." Thus far the Midrash.
