"If you lend money to My people, the poor among you"Exodus 22:24.

We are commanded to lend money to the impoverished, in order to help relieve them and ease their burden. This mitzvah is even greater than that of giving charity; for one who has already reached the point where he has to openly ask people for money is less bothered and pained by [having to ask for assistance] than one who has not yet reached this level. He therefore needs assistance to keep his situation from being known and reaching such a level.
