Deuteronomy 15:9-10

9Beware lest there be a wicked thought in your heart, saying, ‘The seventh year, the year of release, is at hand,’ and your eye be evil against your poor brother and you give him nothing, and he cry out to the Lord against you, and it become sin among you.

10You shall surely give to him, and your heart should not be grieved when you give to him, because for this thing the Lord your God will bless you in all your works and in all to which you put your hand.
