DEUT1693 … if a man were free from labor and did not have to exert himself for his food, he would be recalcitrant and would pursue transgression, as it is written [this verse]: "And Yeshurun grew fat and he kicked." And our Rabbis of blessed memory have said (Avos 2:2): "The ideal is study of Torah combined with the pursuit of a livelihood, for the exertion required by both causes one to forget transgression." But now the Exalted God has relegated two occupations to man, his own and that of Torah. And a man must follow the middle course between the two occupations and devote specified hours to the work of Torah and to the work of this world respectively.
