And our Rabbis said (Midrash Mishlei, ch. 28): “A man of faithfulness will have many blessings” (Mishlei 28:20): this is one who does business faithfully, whose possessions increase, and HaKadosh Baruch Hu arranges his livelihood for him. And not only that: he is called a tzaddik, as it says, “And the righteous one will live by his faith” (Chavakuk 2:4). And our Rabbis said (Makkos 24a): There are six hundred and thirteen mitzvos, etc., and Chavakuk came and summed them up in one, as it says, “And the righteous one will live by his faith.”
