To the conductor, fortunate is he who considers the poor. This refers to what is written in Ecclesiastes 9:14, "A small city with few people in it." The small city refers to a person, and the few people in it are the limbs of the body. And a great king, the evil inclination, comes to it and surrounds it with great fortifications like a mighty army. (ibid. 15) "And he found there a poor man," this refers to the good inclination, who has no one to listen to him in the world. And he saved the city. David said, "Since not everyone listens to him, it is good for me to listen to him." This is what is written, "fortunate is he who considers the poor."
Fortunate Is the One Who Considers the Poor
