Halakhah sa Oseas 9:4: Mishneh Torah, Rest & Kitzur Shulchan Arukh

The children, for example, should be given parched grain, nuts, and sweetmeats; the womenfolk should be presented with pretty clothes and trinkets according to one's means; the menfolk should eat meat and drink wine, for there is no real rejoicing without the use of meat and wine. While eating and drinking, one must feed the stranger, the orphan, the widow, and other poor unfortunates. Anyone, however, who locks the doors of his courtyard and eats and drinks along with his wife and children, without giving anything to eat and drink to the poor and the desperate, does not observe a religious celebration but indulges in the celebration of his stomach. And about such is it stated (Hosea 9:4), "their sacrifices are like the bread of mourners, all who eat it will be contaminated; for their bread is for their own appetites." Such joy is a disgrace for them, as it is stated (Malakhi 2:3), "I will spread dung on your faces, the dung of your festivals."

And when you eat and drink, it is your duty to provide also for the orphan, the widow and other needy people, as it is said, "And the Levite, the proselyte, and the orphan etc…." (Deuteronomy 16:14). He who locks the doors of his courtyard, and eats and drinks with his wife and children and does not give food and drink to the poor and unhappy souls, is not rejoicing in a mitzvah, but rejoicing in his gluttony. Concerning such people it is said,¹⁹Hosea 9:4. "Their sacrifices will be to them like the bread of mourners; all who eat of them will be unclean; for their bread will be for their souls." And such rejoicing is a disgrace for them as it is said,²⁰Malachi 2:3. "I will spread dung on your faces, the dung of your festival offerings."
