Deuteronomy 15:9-10

Beware that there is no wicked thought in your heart, saying, ‘The seventh year, the year of release (remission, pardon), is approaching,’ and your eye is hostile (unsympathetic) toward your poor brother, and you give him nothing [since he would not have to repay you]; for he may cry out to the LORD against you, and it will become a sin for you. You shall freely and generously give to him, and your heart shall not be resentful when you give to him, because for this [generous] thing the LORD your God will bless you in all your work and in all your undertakings.
