Sforno on Deuteronomy 8:7/ספורנו על דברים ח׳:ז׳

1אל ארץ טובה, a land which is the confluence of numerous good, desirable qualities not found together in other districts of the globe. These qualities are the following, the Torah prefacing each with the word ארץ again. 1) ארץ נחלי מים עינות ותהומות, not the waters from polluted rivers or static ponds, waters described as evil waters in Kings II 2,19. 2) ארץ חטה ושעורה , crops which are basic as food. 3) ארץ זית שמן ודבש, products fit for the palate of a king. 4) ארץ אשר לא במסכנות תאכל בה לחם, a land in which money can be found cheaply, a land full of treasures as per Isaiah 2,7 “the land is full of silver and gold and there is no end to the treasures it hides.” Dearth of money is more serious than shortage of the products which can be bought with it, as we know from the Talmud Taanit 19 which declares that whereas the blowing of the shofar in supplication to G’d on account of a shortage of foodstuffs does not have to be arranged immediately, shortage of money, i.e. people not having the money to buy the available food products gives rise to immediate supplication to Gd including the sounding of the shofar at public prayer meetings. 5) ארץ אשר אבניה ברזל, a land whose stones contain iron, i.e. a useful metal, or whose stones are strong as iron, providing excellent building materials.
