Corazón perverso se apartará de mí; no conoceré al malvado.
O coração perverso se afastará de mim; não conhecerei ao mau.
Le cœur pervers s’ éloignera de moi;
Ein verkehrtes Herz muß von mir weichen; den Bösen leide ich nicht.
Het verkeerde hart zal van mij wijken; den boze zal ik niet kennen.
Il cuor perverso s’allontanerà da me; il malvagio non lo conoscerò.
Serce przewrotne odstąpi odemnie, a o złe nie będę dbał.
ибо исчезли, как дым, дни мои, и кости мои обожжены, как головня;
彎曲的 心思，我必遠離；一切的惡人（或譯：惡事），我不 認識。
The false heart I will send away from me: I will not have an evil-doer for a friend.

Scholars' Consensus
Commentators agree this verse is part of David's solemn vow, likely composed as he prepared to bring the Ark to Jerusalem (Calvin; Keil & Delitzsch). The central question is whether 'perverse heart' refers to David's own disposition or to wicked people in his court. The Cambridge Bible and Jamieson-Fausset-Brown read it personally: David will banish perversity from his own heart. Barnes, Clarke and Wesley understand it as a public policy: he will not appoint or associate with the morally crooked. Calvin and Gill see both dimensions, the king's inner resolve and his administrative practice. The Hebrew word ʿiqqēsh (twisted, crooked) denotes a fundamental moral distortion (Proverbs 11:20). David's statement 'I will not know evil' (using yāda‘, intimate acquaintance) is stronger than mere avoidance: it means he will not recognise, approve or fellowship with evil. All traditions view this as a serious commitment to separate from what God hates.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Personal purity view: David resolves to banish perversity from his own heart; supported by Cambridge Bible and Jamieson-Fausset-Brown, reading the Hebrew as self-imprecatory.
- Court administration view: David purges wicked people from his service; supported by Barnes, Wesley, Clarke, and the immediate royal context of vv.2–8.
- Synthetic view: Both personal and public readings are intended; supported by Calvin and Gill, noting that David's inner holiness necessarily shapes whom he appoints.
What is clear: David makes a decisive break with moral crookedness and evil—whether understood as inner disposition or public association—and this break is a necessary condition for living in God's presence.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Object of 'perverse heart' | It describes moral crookedness that is an abomination to God (Proverbs 11:20). | Some read it as David's personal resolve to banish perversity from his own heart (Cambridge, JFB); others as a royal policy to remove crooked people from his service (Barnes, Wesley, Clarke). |
| Meaning of 'I will not know' | The Hebrew verb <em>yāda‘</em> implies more than intellectual awareness, it includes recognition, intimacy and approval. | Catholic and many Protestant traditions emphasise the relational dimension: to 'know' evil would mean to fellowship with it or give it a place. The exact boundary (personal acquaintances vs. court officials) remains disputed. |
| Context: royal court or general piety? | The surrounding verses (vv.2, 8) clearly describe a king's administration, hiring, firing, judging. | Some (Calvin, Gill) treat it as a model for all believers, not just kings. Others (Keil & Delitzsch, Luther) restrict its primary application to theocratic leadership. |
| Application for Christians today | All traditions agree that God's people must separate from persistent, unrepentant evil. | The degree of separation varies: some practice church discipline and selective fellowship; others emphasize mission to the perverse while guarding personal holiness. |
Historical & Cultural Context
Psalm 101 is often called the 'prince's psalm' or 'mirror for monarchs' (Luther). Keil & Delitzsch place it during the early years of David's reign, when the Ark was still in the house of Obed-Edom. David longs for God's presence ('When will you come to me?' in v.2) and sets out his governing principles in response. The cultural context is a royal court: a king's advisors, officials and servants shape the moral character of his rule. Ancient Near Eastern kings routinely published 'justice edicts' to demonstrate their commitment to right order, this psalm reads like a theocratic version of that genre. The 'perverse heart' (lēbab ʿiqqēsh) echoes the wisdom tradition (Proverbs 8:13, 11:20), where the crooked heart is an abomination to the Lord. David's vow is concrete: he will exclude the morally twisted from positions of influence, protect the faithful (v.6), and 'morning by morning' execute justice (v.8). This is not merely personal piety but a programme for the city of God, Jerusalem must mirror God's holiness.
Textual Notes
The consulted sources note no significant textual variants for Psalm 101:4. The Hebrew text is stable across manuscripts, and the translations reflect a uniform reading: 'perverse heart will depart from me; I will not know evil.' The only minor variation is whether the second line refers to 'evil' as a thing or 'a wicked person' (the KJV reads 'wicked person,' while the BSB reads 'nothing of evil'). Both are within the semantic range of the Hebrew ra‘.
Reception History
From early in the Christian tradition, Psalm 101 was read as a king's pledge of righteous governance. Augustine understood the 'perverse heart' as the devil or the unbelieving, who must depart from the faithful. In the Reformation, Luther titled it 'the prince's psalm' and commended it to civil rulers. It was reportedly sent by Duke Ernest the Pious to a faithless minister as a rebuke. Later Protestant commentators (Matthew Henry, Wesley) applied it to every head of a household as a pattern for domestic discipline. Modern interpreters across traditions use the verse to speak about the necessity of character in leadership, transforming it from a political document into a call for personal integrity and relational boundaries.
Preaching This Verse
Three-point outline
- The shape of a perverse heart. The Hebrew word ʿiqqēsh means twisted or crooked, a will that refuses moral straightness. This is not a slip but a settled orientation.
- The distance that holiness requires. David says it 'will depart from me' and 'I will not know evil.' To 'know' (yāda‘) implies intimate acquaintance and approval. He cuts off both the thing and the relationship.
- The cost of covenant leadership. David binds himself publicly. This vow shapes his court, his friendships and his daily judgment (v.8). Leadership that honours God cannot make peace with what He hates.
Five-point outline
- Read the context. Verse 4 sits inside a royal oath (vv.2, 8). David is not describing what he wishes but what he will do.
- Name the enemy within. The perverse heart is a disposition, not just a person. David includes his own heart in the scope of reform.
- Reject the evil companion. Most commentators (Barnes, Wesley, Clarke) hear a royal policy: wicked people will not serve in his court or sit at his table.
- Understand 'not know.' This is stronger than ignorance, it is non-recognition, non-endorsement, non-fellowship.
- Apply the pattern. For pastors, parents and leaders: where do we tolerate what is crooked because it is convenient or familiar?
Illustration hooks
- Employee screening. A hiring manager reviews applicants and chooses not to bring in someone with a pattern of dishonesty, even if they are talented.
- Family boundaries. A parent decides which friends their child can spend time with, not out of snobbery but because influence matters.
- Church membership. A congregation decides someone cannot hold office while refusing accountability or persisting in known sin.
Questions your congregation is asking
- Is it possible to love sinners and still 'not know' evil? How do we tell the difference?
- Does this verse mean we should cut off every friend who struggles with sin? Where is the line between healthy separation and judgmentalism?
- How can I apply this to my own heart, the 'perverseness' I might not even see, without becoming obsessive?
Leading a Discussion
Psalm 101 is a royal vow. In verse 4, David makes a sharp commitment regarding the perverse heart and evil. As you study this together, notice that the Hebrew word for 'know' (yāda‘) carries the weight of intimate relationship and approval. David is not saying he will be ignorant, he is saying he will not fellowship with moral crookedness.
Discussion questions
- How does the surrounding context (vv.2, 3, 5, 8) shape your understanding of what David means by 'perverse heart'?
- Read Proverbs 11:20 and 8:13. What do these proverbs add to our picture of the perverse heart? Why does God treat it as an abomination?
- The Hebrew verb yāda‘ ('know') covers everything from sexual intimacy to judicial recognition. In this verse, which nuance fits best, and why does it matter?
- Some commentators (Barnes, Wesley) read this as excluding wicked people from the royal court; others (Cambridge, JFB) read it as David's personal renunciation. Which reading seems stronger from the text? Can both be true?
- David says 'it will depart from me.' Is that a command, a promise, or a prayer? How do we make perversity depart from our own lives?
- Jesus quoted a similar phrase in Matthew 7:23 ('I never knew you; depart from me'). How does Psalm 101:4 point forward to the final separation between good and evil?
- Where in your life, home, workplace or church, does this verse challenge you to draw a firmer line with what is morally crooked?

What the Commentators Say
11 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke highlights the psalmist's firm resolve to exclude the rash and wicked from any position of trust or friendship. He will not employ them, countenance them, or even acknowledge them personally. Evil itself becomes an object of his determined abhorrence.
Barnes' Notes on the Bible Protestant 1832
Barnes interprets "froward heart" as a perverse, deceitful person. He argues the psalmist's resolve is not about his own character but about who he admits into his home and employ. A family head must exclude the wicked from both friendship and service, whatever their rank or charm.
Calvin's Commentaries Reformed 1564
Calvin sees David writing this psalm before he actually ruled, as a personal vow and preparation for kingship. When David sings of mercy and judgment, he is solemnly declaring his commitment to be a just and upright ruler. Calvin rejects the view that this is simply praise for how God dispenses both kindness and punishment.
Cambridge Bible for Schools and Colleges Anglican 1880
The commentator emphasizes David's personal determination to cleanse his heart from every form of crookedness and perversity as preparation for God's presence. He renders the line "Evil I will not know," underscoring a conscious refusal to tolerate moral corruption within himself.
Geneva Bible Notes Reformed 1599
A froward heart shall depart from me: I will knowe none euill.
Gill's Exposition of the Bible Baptist 1748
Gill describes a person with a froward heart as one who devises and speaks perverseness, contrary to God's law, the Gospel, and all good order. Such a person Christ hates and will bid to depart. When Christ says he will not know a wicked person, Gill means he will have no familiarity, affection, or approval of them, especially at the final judgment.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB links the froward heart to perversity, then stresses the psalmist's firm resolve: he will not indulge such a temper, nor will he even acknowledge evil. The point is that the godly person refuses not only wicked actions but also any inward familiarity with wrong.
Keil & Delitzsch OT Commentary Protestant 1876
Keil and Delitzsch tie this psalm to the time when David left the Ark at Obed-Edom's house and cried out, "When wilt Thou come to me?" They see it as David's vow to walk in holiness and justice, longing for God's presence to dwell in Jerusalem as his royal city.
Lange's Commentary Reformed 1857
Lange sees the psalm as a theocratic king's specific vow to wield royal power for God's holiness in Jerusalem. He argues mercy and judgment are divine attributes to be praised, not a summary of human virtues. The resolves cover personal conduct, court associates, and purging evil from the city of God.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Matthew Henry sees David's choice to sing of both mercy and judgment as reflecting the mixed nature of God's providence in every believer's life. For Henry, the psalm presents David as a pattern for rulers and householders, acknowledging that God's dealings are a blend of hardship and favour, and both deserve praise.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley interprets "depart" as being expelled from Christ's royal court, and "know" as Christ not owning or countenancing the person. These terms carry the weight of a sovereign disowning someone from his presence and favor.
