Deuteronomy 15:9-11

9Take care lest there be an unworthy thought in your heart and you say, 'The seventh year, the year of release is near,' and your eye look grudgingly on your poor brother, and you give him nothing, and he cry to the Lord against you, and you be guilty of sin.

10You shall give to him freely, and your heart shall not be grudging when you give to him, because for this the Lord your God will bless you in all your work and in all that you undertake.

11For there will never cease to be poor in the land. Therefore I command you, 'You shall open wide your hand to your brother, to the needy and to the poor, in your land.'
