Deuteronomy 15:9

Be careful! Don't say to yourself, “Soon it will be the seventh year, and then I won't be able to get my money back.” It would be horrible for you to think that way and to be so selfish that you refuse to help the poor. They are your relatives, and if you don't help them, they may ask the LORD to decide whether you have done wrong. And he will say that you are guilty.
