A Warning Against Cursing the King
20Don’t curse the king, no, not in your thoughts; and don’t curse the rich in your bedroom, for a bird of the sky may carry your voice, and that which has wings may tell the matter.
Ecclesiastes 10:20 warns against harboring contempt for the king even in one's private thoughts, since hidden attitudes inevitably become public through speech and action. The passage emphasizes that interior defiance toward authority is unwise and dangerous, as nothing remains truly secret.
Contempt for authority, even in the privacy of your own mind, breeds a contemptuous character—and contempt never stays hidden for long.
Catholic tradition illuminates this verse at several levels simultaneously.
On Authority: The Church's social teaching, rooted in Scripture and developed through centuries of reflection, holds that legitimate civil authority participates in God's own governance of the world. Romans 13:1 states that "there is no authority except from God," and the Catechism (CCC 1897–1899) affirms that authority is necessary for the common good and derives its moral force from its orientation to that good. Qoheleth's warning against cursing the king is thus not mere court etiquette; it reflects a theological conviction that contempt for legitimate authority disorders the moral self and dishonors the God who ordains order.
On Interior Sin: The verse's emphasis on thought is of particular theological weight. The Catholic tradition, especially as articulated by St. Thomas Aquinas (Summa Theologiae I-II, q. 74), teaches that sin begins in the intellect and will before it reaches the tongue or hand. The Catechism (CCC 1853) distinguishes sins by their object, and CCC 2479 specifically identifies detraction and calumny — including in thought — as violations of justice and charity. Qoheleth anticipates the full moral psychology of Catholic teaching: interior dispositions matter before God.
On Prudence and Discretion: St. John Chrysostom (Homilies on Matthew) and St. Ambrose (De Officiis) both emphasize that the wise Christian governs the tongue by first governing the heart. The Catechism (CCC 2520) calls "purity of heart" the precondition for seeing God, and this verse locates that same discipline in the realm of civic and political life. True prudence begins in the concealed chambers of the mind.
For contemporary Catholics, this verse cuts against the grain of an age that normalizes the venting of contempt for leaders — political, ecclesial, or otherwise — as a form of authenticity or righteous anger. Social media, in particular, has created spaces where cursing leaders "in thought" has become cursing them in full public view, often with thousands of witnesses.
Qoheleth's warning invites the Catholic reader to a more demanding self-examination: not merely "Did I say something I shouldn't have?" but "What is living in my inner world?" Contempt, once entertained habitually, reshapes the character. It breeds cynicism, corrodes charity, and — as the proverb of the bird reminds us — eventually escapes containment.
This is not a call to blind deference or silence in the face of genuine injustice; Catholic tradition, especially the prophetic tradition, has always distinguished just critique from corrosive contempt. Rather, it is a call to examine the spiritual quality of one's political and ecclesial interior life. Is the criticism one offers rooted in a desire for the common good — or in pride, resentment, and the quiet pleasure of tearing down? The bird will eventually carry the answer into the open.
Commentary
Literal Meaning and Narrative Flow
Ecclesiastes 10:20 sits at the close of a extended meditation on wisdom, folly, and political order (10:1–20). The Preacher (Qoheleth) has been cataloguing the absurdity of fools placed in high positions (vv. 5–7), the dangers of careless labor (vv. 8–11), and the destructive speech of the foolish (vv. 12–15). The chapter culminates here with a warning that unifies these threads: even private contempt for authority is dangerous and unwise.
The Hebrew underlying "in your thoughts" (bəmadda'ăkā, literally "in your knowledge" or "in your consciousness") is striking. Qoheleth does not merely caution against public slander or seditious speech — he reaches inward to the seat of deliberate thought. The word madda carries the sense of an interior knowing, a private awareness. The warning is thus radical: do not permit contempt for the king to take root even where no ear can hear it.
The famous folk maxim that follows — "a bird of the air will carry your voice" — is among the most memorable images in all of Wisdom literature. Whether understood literally (the ancient Near Eastern fear of spies and informants, ever-present in royal courts) or metaphorically (the inexorable way that interior attitudes eventually surface in word and deed), the proverb carries the same weight: nothing is truly hidden. The "winged creature" (ba'al hakkənāpayim, literally "a master of wings") will bear the word away. Secrets have a life of their own.
Typological and Spiritual Senses
At the allegorical level, the Church Fathers consistently read "the king" in Wisdom literature as a figure pointing toward God and, in the New Testament, toward Christ the King. To curse the king — even in thought — thus becomes an image of the interior rebellion against God that Catholic tradition calls the "first movement" toward sin. St. Gregory the Great, in his Moralia in Job, frequently insists that disordered interior thoughts, if entertained, become the seedbed of graver sins. Qoheleth's warning anticipates the Sermon on the Mount's logic: it is not enough to refrain from murder; one must not harbor contemptuous anger in the heart (cf. Matthew 5:21–22).
The motif of the revealing bird also carries a deeper typological resonance. In patristic reading, birds often symbolize angels or the action of divine providence. Nothing spoken — or even thought — in secret escapes the sight of God (cf. Psalm 139:1–4). The "winged creature" thus becomes a figure for divine omniscience, a reminder that the court of heaven sees what the court of earthly kings does not.
