It is a widespread custom in Jewish homes that just before we begin our evening meal in the Sukkah, we invite the holy Ushpizin (guests), beginning with our Patriarchs Abraham, Isaac, and Jacob. This custom is first mentioned in the Zohar, which states that one must invite to his home the "upper-world guests" – and after them he must invite "mortal" guests, those who are needy. Inviting the poor and hungry into our home, especially on festivals, is a Torah command, as the Rambam writes: "One must feed the foreigner, the orphan and the widow, together with other poor people – and one who closes off his yard and eats and drinks only with his children and wife without giving food and drink to the poor and bitter-hearted, is not engaging in the Torah-commanded holiday joy, but is rather gladdening only his own belly."
