Deuteronomy 15:7-9

7This is what you must do whenever there are poor Israelites in one of your cities in the land that the Lord your God is giving you.

8Be generous to these poor people, and freely lend them as much as they need. Never be hard-hearted and tight-fisted with them.

9When the seventh year—the year when payments on debts are canceled—is near, you might be stingy toward poor Israelites and give them nothing. Be careful not to think these worthless thoughts. The poor will complain to the Lord about you, and you will be condemned for your sin.
