The Medrash Rabbah (15:6) connects this verse to the pasuk in Tehillim (34:10): “Fear Hashem, His holy ones; for there is nothing lacking for those who fear Him.” We may ask what the connection is between the two pesukim?
Sefer Tiferes Shmuel explains that the root of mitzvos is emunah, as Dovid Hamelech says (Tehillim 119:86): “All of your mitzvos are emunah.” The mitzvah of lighting the Menorah in particular symbolizes emunah. This is seen from Chazal, who say (Shabbos 22B) that the cup on the western side of the Menorah was filled with the same amount of oil as the others but the kohen “would light the others from it each day and with it he would conclude.”
In other words, the rest of the lamps burned throughout the night and went out by morning. The westernmost lamp would continue burning throughout the day after all the others were extinguished and would be used to relight the other lamps each night.
This is a lesson in emunah and Divine Providence. This lamp did not have any more oil than the others, but Hashem gave it the ability to burn longer and to be used to light the others the next night. A person can learn from this that Hashem will provide for him and give him the ability to do what he needs to do.
If a person thinks he doesn’t have time to daven with a minyan because he needs to run to work. He should recognize that he won’t lose anything by serving Hashem. He should spend the time to daven properly and have emunah that Hashem will provide for him and send him parnassah and he won’t lose anything if he trusts in Hashem.
This is the intention of the Medrash. The mitzvah of the Menorah represents emunah; therefore, it is connected to the pasuk that says that those who fear Hashem will never lack anything. This pasuk tells us that one who has emunah will never lose out by fearing Hashem and strictly keeping His mitzvos.
