DEUT398 … with a growing knowledge of Torah, a person's confidence in his own strength and ability is weakened. An overweening sense of self-sufficiency is the worst of sins. It is the wicked person who says, "My strength and the power of my hand have gotten me all this wealth" [this verse]. The man of Torah, however, realizes how much the human being is in the hands of the Creator of all things, dependent on His grace. As his knowledge of Torah grows, a person cannot overrate human power and wisdom.
