Deuteronomy 15:9-10

Watch 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. You must surely give to him, and your heart is not to be grieved when you give to him—for because of this thing ADONAI your God will bless you in all your work and in every undertaking of your hand.
