“As it says, ‘Who among you fears Hashem, etc.’”: Its meaning by the derash: “Who among you fears Hashem,” to come to the beis knesses, “listening to the voice of His servant,” the servant of HaKadosh Baruch Hu, that is, the shaliach tzibbur, who in his prayer performs a service [like] the service of the Kohen Gadol, as it is written (Taanis 2a): “And to serve Hashem your G-d with all your heart” (Devarim 11:13): what is the service that is in the heart? You must say, this is prayer. “Who now walks” in a way of darkness and gloom, that is, he held back from going to it [the beis knesses] for a matter that “has no light,” that is, for an optional matter; which leaves out one who held back from the beis knesses because he went for a mitzvah, for then “he has light,” on the basis of “For a mitzvah is a lamp” (Mishlei 6:23), since then he is occupied with a mitzvah and is exempt from prayer. And since a person may think that this too is a matter of a mitzvah for him, when he goes about his business to profit by it and to support the people of his household, therefore it says, “Let him trust in Hashem”: he should have trusted in Hashem that He would give him his parnassah, and he should not have held back from the beis knesses; as we say below, in Perek Ein Omdin (Berachos 32b), about the early chassidim. And this is easy to understand.
