Deuteronomy 15:9-10

9 Beware that there be not a thought in your wicked 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 to the LORD against you, and it be sin to you.

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