Deuteronomy 15:8-9

8Rather, you must surely open your hand to him and you must surely lend him enough for his need—whatever he is lacking.

9Watch yourself, so there is no unworthy thing in your heart saying, ‘The seventh year, the year of cancelling debts, is near,’ and your eye is evil against your poor brother and you give him nothing. Then he may call out to Adonai against you, and it will be a sin upon you.
