Proverbs 6:18 warns that wickedness begins in the heart and shows up in the feet, meaning in the plans a person makes and the paths they choose to walk. The verse is part of a list of things the LORD hates, and it describes the kind of person who quietly plots harm and then hurries to carry it out. It comes from the book of Proverbs, a collection of wise sayings traditionally attributed to Solomon and addressed to a young man who is being urged to choose the way of wisdom.
A heart that devises wicked schemes, feet that are swift in running to mischief…

What Proverbs 6:18 Means
The verse uses two body parts to describe a single problem. The “heart” is where the verse places the origin of evil: the imagination, intention and planning that come before any action. The phrase “devises wicked schemes” pictures someone working out a harmful plan carefully, turning it over in the mind until it is ready to be put into practice.
The “feet that are swift in running to mischief” describe what happens next. Once the scheme is formed, the person acts on it eagerly, almost without hesitation. The picture is of someone who not only thinks about doing wrong but is quick and willing to rush toward it.
The verse does not promise that every wrong thought will be punished in exactly the same way, and it does not say that a person can never change direction. What it does is name clearly where sin starts and how it grows, so that the reader can recognize the pattern in themselves before it becomes a habit.
The Context of Proverbs 6:18
The verse sits inside a longer passage in which the teacher warns a young man against becoming entangled in dishonesty, careless promises and destructive relationships. Just before verse 18, the list names haughty eyes, a lying tongue and hands that shed innocent blood, and the verse adds to that list by pointing inward to the heart. Just after, the father urges his son to keep his parents’ teaching close and to bind it on his heart and neck, a deliberate contrast to the schemes the verse has just described.
Because of this setting, the verse reads less like a general statement about human nature and more like a practical warning to a learner. The surrounding words show that the wise response to wickedness is not only to avoid bad actions but to guard the inner life and to hold firmly to instruction that shapes the heart in the opposite direction.

Jeremiah 17:9
The heart is deceitful above all things and it is exceedingly corrupt. Who can know it?

This verse describes the human heart as deceitful and desperately sick, which helps explain why Proverbs 6:18 locates the source of wrongdoing so precisely. It reminds the reader that the heart needs more than self-correction and points toward dependence on God for an honest inner life.
Psalm 51:10
Create in me a clean heart, O God. Renew a right spirit within me.

David’s prayer for a clean heart and a steadfast spirit answers the problem Proverbs 6:18 exposes. Where the proverb names the scheming heart, the psalm shows the kind of request that a person can bring to God when they recognize that their inner life needs renewal.
A Short Prayer From Proverbs 6:18
Lord, you know the thoughts I have not spoken and the plans I have quietly turned over in my mind. Search my heart and show me where I have begun to devise anything that would hurt another person or dishonor you. Slow my feet when they are eager for what is wrong, and turn my intentions toward what is good and true. Keep my heart close to your teaching, so that I may walk in the way that pleases you. Amen.
