Proverbs 23:19–21

In three terse lines, the sage-father calls his son to wisdom by steering him away from the company of drunkards and gluttons, warning that intemperance leads inevitably to material ruin. The passage belongs to the extended "father's instruction" section of Proverbs (chs. 22–24) and distills one of ancient Israel's enduring convictions: that bodily self-mastery is inseparable from the life of wisdom, and that disordered appetite is its own punishment.

Verse 19 — "Listen, my son, and be wise" The imperative shema ("listen/hear") is the foundational act of Israelite wisdom and piety, echoing the Shema of Deuteronomy 6:4. Its use here signals that what follows is not merely practical advice but a demand for the whole person's attentiveness. The sage's address "my son" (Hebrew beni) frames the relationship not as that of a detached teacher but as a father shaping a child's character — a literary and pedagogical device that runs throughout Proverbs 1–9 and reappears in these middle chapters. Crucially, the son is told to "be wise" (v'asher libbeka, literally "set your heart on the right path"), locating wisdom not in the intellect alone but in the lev — the heart, the seat of will, desire, and moral discernment in Hebrew anthropology. This verse is therefore not merely an introduction; it frames the entire moral exhortation as a matter of the heart, of rightly ordered desire.

Verse 20 — "Don't be among ones drinking too much wine" The Hebrew construction (al-tehi besovei yayin, "do not be among those who consume wine to excess") is notable for its social dimension: the prohibition is not simply against private drunkenness but against joining the company of the intemperate. The sage recognizes that vice is contagious and that the formation of character depends heavily on one's associations. This is consistent with a broader Proverbs motif: one becomes like those with whom one dwells (cf. 13:20, "Walk with the wise and you will be wise; associate with fools and you will go astray"). The specific mention of wine does not imply total abstinence — wine is celebrated elsewhere in the Old Testament as a gift of God (Ps 104:15) — but excess (sava', surfeit, gorging) is the target. The parallel warning against those who are "gluttonous with meat" (zolalei basar) confirms this: the evil is disordered consumption, not the created goods themselves.

Verse 21 — "For the drunkard and the glutton shall become poor" The sage grounds the warning in observable consequence: the sovei yayin (wine-saturated) and the zolel (the gorger, the prodigal) will end in poverty. The word zolel is significant — it is the same root used in Deuteronomy 21:20, where rebellious sons are condemned before the elders as "gluttons and drunkards" (zolel v'sovei). The sage is drawing on a legal-traditional vocabulary of moral failure. The consequence — poverty — operates on two levels simultaneously. At the literal level, intemperance squanders resources. At the metaphorical and spiritual level, the "poverty" of the intemperate person is also a poverty of soul: the person who cannot govern appetite becomes enslaved to it, incapable of the free, ordered self-gift that constitutes genuine human flourishing. The verse thus points beyond economics toward a vision of the human person as one called to mastery over passion — a love, not merely want.

Catholic tradition receives this passage as a Scriptural warrant for the cardinal virtue of temperance, one of the four natural virtues that reason can discern and grace perfects. The Catechism of the Catholic Church defines temperance as "the moral virtue that moderates the attraction of pleasures and provides balance in the use of created goods" and explicitly applies it to "the use of food and drink" (CCC §1809). Far from a merely negative restraint, temperance in Catholic thought is ordered toward flourishing: it "keeps desires within the limits of what is honorable" (CCC §1809), enabling the person to live freely rather than as a slave to passion.

St. Thomas Aquinas, following Aristotle but baptizing the insight, treats gluttony and drunkenness as species of the vice opposed to temperance. In the Summa Theologiae (II-II, q. 148), he identifies gluttony as a capital sin precisely because disordered appetite for food and drink generates further vices — sloth, lust, and a dulling of the mind to spiritual goods. This is exactly the trajectory Proverbs warns against: the drunkard does not merely lose money; he loses the lev, the heart rightly ordered toward wisdom.

St. John Chrysostom preached vigorously on intemperance, noting that drunkenness is an especially grave spiritual danger because it extinguishes the light of reason by which we apprehend God: "Wine was given to gladden the heart, not to quench the mind" (Homilies on Matthew, 57). St. Basil the Great connects gluttony directly to the Fall, arguing that disordered eating was humanity's primal sin (cf. Homily on Fasting), making temperance in food and drink an act of reparation and spiritual recovery.

The social dimension of verse 20 — do not be among them — also resonates with Catholic moral anthropology's emphasis on community formation. We are shaped by our associations; this is why the Church's tradition of fasting and abstinence (cf. CIC c. 1249–1251) is not merely individual discipline but a communal practice of ordered eating that forms the People of God in virtue together.

Contemporary Catholic life is saturated with invitations to excess: binge culture, the normalization of drunkenness as social bonding, and food as emotional self-medication. Proverbs 23 speaks with startling directness into this environment. The sage's warning to avoid the company of the intemperate is countercultural wisdom: it means being willing to leave early, decline the third round, or skip the culture where overeating and heavy drinking are the price of belonging. This is not priggishness — it is the claim that our associations form us.

For Catholics, the practice of the Friday fast and the Eucharistic fast before Mass are not relics but living schools of temperance — small, regular acts of governing appetite that train the heart (the lev) for larger freedoms. The person who cannot say no to a second drink is unlikely to say yes to costly love. Concretely: consider recovering the practice of Friday abstinence not merely as rule-following but as weekly apprenticeship in the freedom that allows one to choose the good. Consider also examining not just your own drinking and eating, but the social environments you inhabit, and whether they are forming you toward wisdom or toward the poverty — financial and spiritual — that the sage warns against.
