Musar su Salmi 112:3

A man should be generous with his money to copy and to purchase books and to lend them to one who has none, as it is said, "Wealth and riches are in his house; and his merit endureth for ever" (Ps. 112:3). And a man should be easygoing and not mind if the books are damaged because of their use (Kethuboth 50a). He should also be generous when it comes to his household utensils, and lend them to his neighbors and his friends.
