Moses makes preparations for himself and for the people and then ascends Mt. Sinai to receive the Ten Commandments. It is an obligatory act, not merely a charitable act, to lend money according to the Torah. If a person borrowed money, spent it and is not able to pay it back when asked, you must not press him. If, however, you lend someone an object, then that object remains in his possession and you are permitted to demand its return. There is an old Jewish custom of establishing gmachs, or freeloan societies.
People donate money to the society which lends money without interest to anyone requesting a loan.
They lend out money for various lengths of time, the average period being a year. The Chofetz Chaim, a great rabbi was once asked by a wagon driver what he could do to ensure a place in the World to Come. Every community should form at least one such society.
