Deuteronomy 15:10-11

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. For the poor will never cease to be in the land; therefore I command you, saying, ‘You shall freely open your hand to your brother, to your needy, and to your poor in your land.’
