Halakhah zu Dewarim 15:11

If you support your grown children whom you are not obligated to support [those over the age of six], in order to teach your sons Torah, and your daughters to lead proper lives, similarly, if you support your father [or mother] (and you are not able to support them except by using your charity money,) and they need this support—this constitutes charity; and what is more, they take precedence over others. Even if it is not a son or a father but only a relative, he takes precedence over anyone else. And the poor person in your your house takes precedence over the poor in your city, and the poor of your city takes precedence over the poor of another city, as it is said: "To your brother, to your poor, to your needy in your land."¹⁸Deuteronomy 15:11. But the treasurer who distributes communal charity, must be careful not to give his relatives more than [he gives] to the other poor people.
