Provérbios 3:33 Halacá: Mishneh Torah, Human Dispositions

Even as the wise man is recognized by his wisdom and ideas, whereby he is distinguished from the rest of the public, so it is necessary for him to be distinguished in his conduct, eating, drinking, sexual relations, elimination, speech, rendevous, dress, temperate in words, and in his business relations. All these deeds should be aesthetic and exceedingly cultured. A disciple of the wise must not be voracious, but eat proper food to strengthen his body; but even of such food he shall not partake a large quantity, nor be after eating in order to have a full stomach, as those who fill themselves up with food and drink until their bellies swell, concerning whom it is traditionally commented saying: "And I will spread dung upon your faces" (Mal. 2.3) refers, according to the sages, to those people who eat and drink and act as if determined to make of their lives a continuous feast.²Shabbat, 15G. And, it is they that say: "Let us eat and drink, for tomorrow we must die" (Is. 22.13), which typifies the way wicked people eat, and it is such festive tables which were shamed in the verse saying: "For all tables are full of vomit, of filthiness, there is no place clean" (Ibid. 28.8). But the wise does not eat save one or two dishes, and of that he eats only enough to sustain his life and is satisfied, which is as Solomon said: "The righteous eateth to satisfy his soul" (Prov. 13.25).
